As stated in the Background Art, the application direction of vertical search engine is a lot, such as enterprise's library searching, supply-demand information search engine, shopping search, house property search, talent's search, map search, mp3 search, picture searching.Give an example and illustrate and to be more readily understood, such as shopping search engine, overall flow is roughly as follows: according to user's searching requirement, after grasping webpage, webpage merchandise news is extracted, extract trade name, price, brief introduction ... even can further the notebook brief introduction be subdivided into " brand, model, CPU, internal memory, hard disk, display screen ... ", and Search Results returned to the user.For searching requirement according to the user, improve the correlativity of return message and the information that is used for searching for, the application has proposed a kind of querying method of vertical search.

The embodiment of the present application provides a kind of querying method of vertical search, as shown in Figure 1, may further comprise the steps:

Step 101, querying server obtain user's Query Information.

Wherein, described Query Information can comprise the query word of described user's input and the commodity classification of user's input or selection.

Step 102, described querying server obtain Query Result according to described Query Information in the queries dictionary of described commodity classification server, described Query Result is commodity class sub-commodity classification and the corresponding weight thereof now that is complementary with described Query Information.

Step 103, described querying server sort the sub-commodity classification in the described Query Result according to its corresponding weight, and ranking results sent to described user, described user is checked, and make log server generate daily record according to commodity classification and the described Query Information that described user checks, and described daily record is sent to Analysis server carry out statistical study and obtain statistic analysis result, described statistic analysis result is used to upgrade the queries dictionary of described commodity classification server, is used for follow-up inquiry.

Wherein, at described querying server before corresponding weight sorts according to it with the sub-commodity classification in the described Query Result, can also set a weight threshold, the sub-commodity classification of the weight in the described Query Result greater than described weight threshold sorted according to its corresponding weight.By the Query Information commodity classification that the inquiry acquisition is complementary in the inquiry dictionary, can sort according to weight to the sub-commodity classification of now all of this commodity class, also can only sort according to weight to parton commodity classification.When parton commodity classification is sorted according to weight, can preestablish a weight threshold, the weight of only choosing in the Query Result sorts according to its corresponding weight greater than the sub-commodity classification of this weight threshold.By parton commodity classification is sorted, and ranking results is sent to the calculated amount that the user can reduce ordering, improve the computing velocity of ordering.

The querying method of a kind of vertical search that provides in the embodiment of the present application, as shown in Figure 2, wherein, querying server is specially commodity classification querying server, Analysis server is specially distributed document storage and concurrent operation platform, as shown in Figure 3, specifically may further comprise the steps:

(1) front-end server receives the Query Information of user's input, comprises query word and commodity classification in the Query Information, and front-end server is transmitted to the log query server with this query word, is used for follow-up according to this time inquiry generation daily record; This Query Information is transmitted to commodity classification querying server, is used for inquiring about according to this Query Information, and Query Result is returned to the user, click for the user and check at commodity classification querying server.

(2) user clicks commodity classification and commodity according to the needs of oneself at front-end server and checks, at this moment, each click checks that action all can generate a corresponding log record by log server, commodity that this daily record has the user to click to check and the commodity classification under this commodity.After a period of time, log server imports to distributed document storage and concurrent operation platform with all daily records in this section period, is used for storage and statistical study to daily record.

(3) the click analytic statistics program in distributed document storage and the concurrent operation platform is carried out statistical study to the daily record in a period of time, this analysis comprises obtains the weight that each commodity classification is clicked, weight has embodied the degree of correlation of commodity classification and user inquiring information, preferably, can be the number of clicks or the click probability of Query Information correspondence.When commodity are checked in user's click, because each daily record all records this time click and checks corresponding user inquiring speech, and commodity classification under the commodity checked of this click, thereby just can obtain the commodity classification and the weight at the commodity place that the user checked according to a large amount of daily records at same query word.Therefrom can know, when the user imports this query word, the degree of correlation of each commodity classification and this query word, the i.e. degree of user's care.Click analytic statistics program as output, is sent to commodity classification querying server with statistic analysis result.

(4) commodity classification querying server passes through the form compiled query dictionary of hash algorithm with Key-Value according to statistic analysis result, thereby improves the speed of inquiry.Wherein Key is the query word of user's input, and Value is a plurality of commodity classifications and the corresponding weights of this query word correspondence, and this queries dictionary has embodied the degree of correlation of query word and each commodity classification.When the query word of knowing the user and commodity classification, promptly can in queries dictionary, inquire about, commodity classification that will be relevant with this query word returns to the user, and according to the height of the degree of correlation, promptly the weight of commodity classification is arranged, and selects for the user.

Need explanation the time, upgrading queries dictionary according to this statistic analysis result can be the queries dictionary that only generates according to the Query Result of this time statistical study, also this time statistic analysis result can be added in the former queries dictionary, generate new queries dictionary, also can delete in the set period as required or set period before statistic analysis result corresponding data in queries dictionary.For example: for the commodity of clothes class, when to season of changing according to the season, statistic analysis result before will not be suitable for inquiry subsequently, thus will be not used in the data deletion of the statistic analysis result correspondence of inquiry subsequently, to guarantee the accuracy of inquiry.

By above-mentioned explanation as can be known, this querying method is a round-robin process.When the user inquired about, to be commodity classification querying server checked inquiry in the queries dictionary that behavior generates and the Query Result that obtains in the click of a last time period to the Query Result that returns; To carry out statistical study in the next time period and in this inquiry, click the daily record that the behavior checked generates, and send to commodity classification querying server, be used for follow-up commodity classification inquiry according to the user.

The embodiment of the present application provides a kind of querying method of vertical search, as shown in Figure 4, may further comprise the steps:

Step 401, user input query information.

Herein, it is query word that our definition is used to carry out the required Query Information of one query, also can comprise the commodity classification.

Front-end server provides with the user and carries out mutual window by query page.The user visits this query page by browser, and the Query Information that input is wanted to inquire about in this query page is inquired about.

For example, when the user need buy a T-shirt, the user logined the online transaction website, and by the query page of this website, the input user wants the Query Information " T-shirt " inquired about.At this moment, when if the user only wants to check the information of relevant men's clothing T-shirt, the combobox that system ejects in the time of can passing through input " T-shirt " is selected the commodity classification, thereby in the input inquiry speech, input commodity classification limits query context, and for example: the user selects " the T-shirt men's clothing " in the combobox, wherein " men's clothing " is the commodity classification, and Query Information is " a T-shirt men's clothing ".

The user is input inquiry speech " T-shirt " only, when providing " men's clothing ", " women's dress " and " easy dress " on the page that system returns according to " T-shirt ", the user selects " men's clothing ", and wherein " men's clothing " is the commodity classification, and Query Information is " a T-shirt men's clothing ".

Step 402, front-end server obtain the Query Information of user's input.

Front-end server gets access to the Query Information of user's input by query page, specifically may further comprise the steps:

(1) front-end server obtains the Query Information of user's input by query page.

(2) front-end server obtains the pairing commodity classification of the commodity classification ID in this Query Information.

Inquiry for the ease of the commodity classification querying server of rear end, front-end server is not directly the commodity classification in the Query Information that is obtained to be sent to commodity classification querying server, but the commodity classification ID of this commodity classification correspondence is sent to commodity classification querying server, so front-end server need obtain the commodity classification ID of this commodity classification correspondence.

At this moment,, do not have the commodity classification, then need not to obtain commodity classification ID if Query Information is a query word only.

Certainly, also can the commodity classification be transmitted to the commodity classification querying server of rear end, obtain the commodity classification ID of this commodity classification correspondence, inquire about by this commodity classification ID again by the commodity classification querying server of rear end by front-end server.

Step 403, front-end server are transmitted to query word in the Query Information and commodity classification ID the commodity classification server of rear end.

The commodity classification querying server of front-end server and rear end carries out the transmission of data by interface.The input and output of front-end interface adopt the mode of http to conduct interviews and return results.Input parameter adopts the http agreement, submits to parameter to give " commodity classification querying server " by the Get mode.The parameter of importing into mainly contains two: query word and commodity classification ID.

The form that input connects is as follows:

Http:// host? query=Cha Xunci ﹠amp; Catid=commodity classification id

Return results adopts the form of XML, and concrete form is as follows:

The commodity classification querying server of step 404, rear end is inquired about, and Query Result is sent to front-end server according to the Query Information that receives.

The Query Result that step 405, front-end server will be sent by the commodity classification querying server of rear end is shown to the user.

Wherein, when Query Information only is query word, all commodity classifications that Query Result is and this query word mates and corresponding weight thereof (being the number of clicks or the click probability of commodity classification), and according to weight series arrangement from high to low; When Query Information is query word and commodity classification, sub-commodity classification of now all of commodity class that Query Result is and this Query Information mates and corresponding weight thereof (being the number of clicks or the click probability of commodity classification), and according to weight series arrangement from high to low.

Preferably, be shown in user's the Query Result page, both comprised the sub-commodity classification of now all of commodity class that is complementary with Query Information, also comprised the detailed list of now each of these sub-commodity classes merchandise news, so that the user directly selects concrete commodity to check in this Query Result.

Step 406, user be according to Query Result, and the commodity classification of therefrom selecting to check is clicked and checked that log server generates daily record according to clicking.

Front-end server is by the Query Result display page, and the Query Result that the commodity classification querying server of rear end is returned is shown to the user.User's commodity classification that selection will be checked from the Query Result that shows is clicked and is checked, clicks in the subcategory of the commodity classification of being checked again, returns to the user for checking by commodity classification querying server according to above-mentioned querying method again.And so forth, find the commodity that to check, click and check by checking the commodity classification step by step.

All added the connection that is saved in " log server " in above-mentioned each shown commodity.In the process that click is checked, after commodity are clicked, all will generate corresponding daily record according to this time click behavior, be kept in the log server.Wherein, click behavior each time is a click logs, and the form of daily record is as shown in table 1:

Table 1 journal format

Query word

The inquiry classification

Commodity ID

The commodity classification

Item property

Wherein, query word is the query word in the Query Information of user's input, the inquiry classification is selected commodity to click for user's commodity classification that selected click is checked in the commodity classification that the page returns and from click the page that this commodity classification returns to check, this moment, this commodity classification was the inquiry classification, so it is a plurality of that the inquiry classification has, and the inquiry classification that the inquiry classification in the daily record is only stored is checked the last before commodity classification of clicking of commodity for the user clicks.After clicking this inquiry classification, the Query Result that returns to the user had both comprised that the sub-commodity classification of now all of this inquiry class also comprised the detailed list of now each of these sub-commodity classes merchandise news.Commodity ID is the pairing ID of each commodity number, is used for each commodity of unique identification.The commodity classification that the commodity that the commodity classification is checked for the user clicks are directly affiliated.This commodity classification may be the sub-commodity classification of inquiry classification.Item property is the pairing satellite informations of these commodity, for example: brand.

For example, when the query word of user's input is " T-shirt ", in the Query Result that the commodity classification that clicks according to the user returns for " long sleeves T-shirt ", having selected a brand in the detailed list of commodity is the T-shirt of POLO, the commodity ID of this part commodity correspondence is 12200021, its directly affiliated commodity classification is the men's clothing T-shirt, and wherein " men's clothing T-shirt " is the subcategory of " long sleeves T-shirt ", generates a log record as shown in table 2 according to above-mentioned information.

Table 2 log record

Query word	The inquiry classification	Commodity ID	The commodity classification	Item property
					T-shirt	The long sleeves T-shirt	12200021	The men's clothing T-shirt	Brand: POLO

Step 407, log server regularly import to the daily record that generates distributed document storage and concurrent operation platform.

Distributed document storage and concurrent operation platform are used to store the daily record of generation, and the calculating when all daily records are analyzed.

The generation of each bar log record is along with user's click checks that log server regularly should all daily records in the time period import to distributed document storage and concurrent operation platform and produced simultaneously.Wherein, the regular operation of log server can be every day, or per 12 hours or the like.

Step 408, click analytic statistics program timing are carried out statistical study to stored log, draw statistic analysis result.

Log server is clicked the analytic statistics program and will regularly be carried out statistical study to stored log after regularly the daily record that generates being imported to distributed document storage and concurrent operation platform, draws statistic analysis result.The object of this statistical study can be nearest ten days daily record, or the daily record in nearest two weeks, and the concrete time can be adjusted according to empirical value or statistical demand.

Concrete, click the analytic statistics program timing stored log is carried out statistical study, draw statistic analysis result, specifically may further comprise the steps:

(1) obtains the daily record of carrying out statistical study.

Log server can regularly upgrade the daily record in distributed document storage and the concurrent operation platform, when click analytic statistics program timing is carried out statistical study to stored log, need obtain the daily record of renewal, to obtain up-to-date daily record, improves statistical accuracy.

(2) query word is carried out normalized.

Because the query word of each user's input not necessarily meets the statistical standard of clicking the analytic statistics program, for the ease of adding up according to query word, need carry out normalized to query word.Normalized comprises removes unnecessary speech in the query word, and the conversion of alphabet size between writing carried out, the conversion between the full-shape half-angle, the conversion between the simplified traditional font, the conversion of punctuate and the conversion between the Chinese figure etc. in unnecessary space.Query word through normalized can be directly used in the statistics of clicking the analytic statistics program.

(3) data are carried out in daily record and gather, generate and click distributed data.

When thousands of user inquires about, can import identical query word and click identical inquiry classification, according to the daily record in a period of time, the query word of user inquiring and inquiry classification are gathered, obtain the number of times of the commodity classification of clicking according to each query word.

For example, click the commodity of checking by query word " T-shirt " and have 400, wherein have 200 commodity to belong to men's clothing commodity classification, have 100 commodity to belong to women's dress commodity classification, have 100 commodity to belong to CRUX commodity classification.In belonging to 200 commodity of men's clothing commodity classification, there are 200 commodity to belong to cotta T-shirt commodity classification, there is 0 commodity to belong to long sleeves T-shirt commodity classification.In belonging to 100 commodity of women's dress commodity classification, there are 100 commodity to belong to cotta T-shirt commodity classification, there is 0 commodity to belong to long sleeves T-shirt commodity classification.In belonging to 100 commodity of CRUX commodity classification, there are 60 commodity to belong to lovers and adorn the commodity classification, there are 40 commodity to belong to motion T-shirt commodity classification.

Above-mentioned each click view procedure and all can generate corresponding daily record, according to the gathering of daily record, draw click distributed data as table 3:

Table 3 is clicked distributed data

(4) obtain commodity classification tree.

For the ease of user's the inquiry and the management of system, all commodity are all classified to it according to attribute, and each commodity all has the commodity classification under it, and all commodity classifications have been generated commodity classification tree according to logical order.

Click the analytic statistics program and want to generate the click tree according to the click distributed data, must know commodity classification residing position in all commodity classifications that the user clicks, promptly set so need obtain the commodity classification position in commodity classification tree.

(5), generate click classification tree according to clicking distributed data in conjunction with commodity classification tree.

Comprise all commodity classifications in the commodity classification tree, and represented relation between each commodity classification visually with the form of tree.Click the commodity classification that distributed data has comprised that all users click, and embodied the number of clicks of each commodity classification with the form of literal.Clicking the classification tree promptly is that the information in commodity classification tree and the click distributed data is combined, with commodity classification tree is the form of expression, all add relevant position in the commodity classification tree to clicking each bar data in the distributed data, the number of clicks of logical relation between the commodity classification of commodity classification tree embodiment and the embodiment of click distributed data is associated, jointly embodies.

At first, generate click classification tree.Construct according to commodity classification and this commodity classification correspondence position in the commodity classification is set clicked in the distributed data, generate and click the classification tree, set as shown in Figure 5 according to the click classification that the click distributed data in the table 3 generates.

Secondly, add the number of clicks of clicking commodity classification in the classification tree.Add the corresponding commodity class of click classification tree to now with clicking the number of clicks of analyzing each commodity classification correspondence in the data, finish the generation of clicking the classification tree, set as shown in Figure 6 according to the click classification that comprises number of clicks that the click distributed data in the table 3 generates.

(6) generate and click classification and set corresponding inquiry file.

The form of clicking the classification tree has embodied user's click information simply, inquiry for the ease of the commodity classification querying server of rear end, the user's click information that comprises in the click classification need being set is with the form performance of text, so according to clicking the classification number, generate corresponding with it inquiry file, be used for the more queries dictionary of new commodity classification querying server.

Need to prove that for clicking the classification tree, when the commodity classification in clicking the classification tree was not checked by user's click, the number of clicks of this commodity classification in clicking the classification tree was zero degree; For inquiry file, when the commodity classification in clicking the classification tree is not checked by user's click, to can not generate and the corresponding inquiry file of this commodity classification number, promptly include only in the inquiry file and click the data message of being clicked the commodity classification correspondence of inquiring about in the classification tree by the user.

According to the click classification tree that comprises number of clicks shown in Figure 6, the inquiry file of generation is:

T-shirt root classification men's clothing: 200 women's dresses: 100 CRUXs: 100

T-shirt men's clothing cotta T-shirt: 200

T-shirt women's dress cotta T-shirt: 100

T-shirt CRUX lovers dress: 60 motion T-shirts: 40

To step 408 (6), finished statistical study by above-mentioned steps 408 (1), drawn statistic analysis result, be i.e. the number of clicks of the logical relation between the commodity classification of the commodity classification of Dian Jiing, click and each commodity classification daily record.

Need to prove that the number of clicks of commodity classification has embodied this commodity classification at commodity at the same level, i.e. weight in parent all subcategories now under this commodity classification.In addition, this commodity classification weight also can embody with the form of clicking probability in parent all subcategories now under this commodity classification, and this clicks the number of clicks acquisition of probability by correspondence.The weight of above-mentioned inquiry file is to click the form body now of probability, and this inquiry file is:

T-shirt root classification men's clothing: 50% women's dress: 25% CRUX: 25%

T-shirt men's clothing cotta T-shirt: 100%

T-shirt women's dress cotta T-shirt: 100%

T-shirt CRUX lovers dress: 60% motion T-shirt: 40%

Step 409, click analytic statistics program with inquiry file are as a result of exported.The inquiry file of this output will send to the commodity classification querying server of rear end, so that the commodity classification querying server of rear end generates corresponding queries dictionary according to this inquiry file, be used for follow-up inquiry.

The embodiment of the present application provides a kind of querying method of vertical search, as shown in Figure 7, may further comprise the steps:

The commodity classification querying server of step 701, rear end is compiled into queries dictionary with inquiry file.

The commodity classification querying server of rear end need be inquired about the commodity classification according to Query Information when the Query Information that the receiving front-end server sends, and qualified Query Result is sent to front-end server.So when the commodity classification server of rear end was inquired about, the commodity classification that at first needs to be used to inquire about was compiled into queries dictionary, so that the commodity classification querying server of rear end is inquired about.

Queries dictionary is obtained by the compiling of queries dictionary program compiler, particularly, the output result (being inquiry file) that queries dictionary program compiler compiling will be clicked the analytic statistics program is compiled into the Memory Mapping File and its of correspondence by the hash algorithm with the form of Key-Value, is used for follow-up inquiry.Wherein Key is the query word of user's input, and Value is a plurality of commodity classifications and the corresponding weights of this query word correspondence.

For example: as follows for the inquiry file that step 408 (6) is generated:

T-shirt root classification men's clothing: 50% women's dress: 25% CRUX: 25%

T-shirt men's clothing cotta T-shirt: 100%

T-shirt women's dress cotta T-shirt: 100%

T-shirt CRUX lovers dress: 60% motion T-shirt: 40%

Wherein, with the queries dictionary that the form of Key-Value is compiled into to be by the hash algorithm:

Key:T sympathizes root classification Value: men's clothing 50%; Women's dress 25%; CRUX 25%;

Key:T sympathizes men's clothing Value: cotta T-shirt 100%;

Key:T sympathizes women's dress Value: cotta T-shirt 100%;

Key:T sympathizes CRUX Value: lovers adorn 60%; Motion T-shirt 40%.

The queries dictionary program compiler is carried out the queries dictionary compiling to the output result queries file of clicking the analytic statistics program, is compiled into hash algorithm Memory Mapping File and its with the form of Key-Value, is used for follow-up inquiry.Need to prove that this hash algorithm Memory Mapping File and its can directly be loaded into internal memory to improve system initialization efficient when program initialization.In addition, for convenience of explanation, commodity classification in the embodiment of the present application all adopts the form of expression of commodity classification title, but in practical operation, the form of expression of commodity classification can be the commodity classification ID of title or this commodity classification correspondence of commodity classification, and wherein the form of commodity classification ID is convenient to the commodity classification is inquired about.

The commodity classification querying server of step 702, rear end regularly loads queries dictionary.

Queries dictionary loads and to be meant when startup of server, the mode by memory-mapped directly with the queries dictionary File mapping of hash algorithm Memory Mapping File and its form compiling to internal memory.

Step 703, user input query information.

Front-end server provides with the user and carries out mutual window by query page.The user visits this query page by browser, and the Query Information that input is wanted to inquire about in this query page is inquired about, and this Query Information is a query word, also can comprise the commodity classification.

For example, when the user need buy a T-shirt, the user logined the online transaction website, and by the query page of this website, the input user wants the Query Information " T-shirt " inquired about.At this moment, when only wanting to check the information of relevant men's clothing T-shirt as if the user, when can pass through the input inquiry speech, input commodity classification limits query context, and promptly in query page input " T-shirt men's clothing ", wherein " men's clothing " is the commodity classification.

Step 704, front-end server obtain the Query Information of user's input and are transmitted to the commodity classification querying server of rear end.

Front-end server gets access to the Query Information of user's input by query page, and is transmitted to the commodity classification querying server of rear end, specifically may further comprise the steps:

Need to prove, do not have the commodity classification, then need not to obtain commodity classification ID if Query Information is a query word only.

Step 705, front-end server are transmitted to query word in the Query Information and commodity classification ID the commodity classification server of rear end.

The form that input connects is as follows:

Http:// host? query=Cha Xunci ﹠amp; Catid=commodity classification id

Return results adopts the form of XML, and concrete form is as follows:

The commodity classification querying server of step 706, rear end obtains Query Information, and the query word in the Query Information is carried out normalized.

Because the query word of each user's input not necessarily meets the query criteria of the commodity classification querying server of rear end, for the ease of inquiring about according to query word, need carry out normalized to query word.Normalized comprises removes unnecessary speech in the query word, and the conversion of alphabet size between writing carried out, the conversion between the full-shape half-angle, the conversion between the simplified traditional font, the conversion of punctuate and the conversion between the Chinese figure etc. in unnecessary space.Can be directly used in the inquiry of the commodity classification querying server of rear end through the query word of normalized.

The commodity classification querying server of step 707, rear end is inquired about in queries dictionary according to Query Information, obtains Query Result.

The commodity classification querying server of rear end is inquired about in the queries dictionary that is loaded by step 702 according to Query Information.Because the mode by memory-mapped directly arrives internal memory to the queries dictionary File mapping with the compiling of hash algorithm Memory Mapping File and its form, so inquire about by using Hash to search at internal memory in the whole query script, guarantees the efficient of inquiring about.

For example: when the query word of user's input was " T-shirt ", the commodity classification querying server of rear end was inquired about according to the queries dictionary that generates in the step 701, and this moment, Key was " T-shirt ", obtained corresponding Value, and promptly men's clothing 50%; Women's dress 25%; CRUX 25%.When the query word of user input be " a T-shirt CRUX " or when clicking commodity classification " operation is lain fallow ", the commodity classification querying server of rear end is inquired about according to the queries dictionary that generates in the step 701, this moment, Key was " a T-shirt CRUX ", obtain corresponding Value, promptly lovers adorn 60%; Motion T-shirt 40%.

By the way, the commodity classification querying server of rear end obtains the Query Result of this Query Information, comprise commodity classification relevant and the pairing weight of each commodity classification in this Query Result with Query Information, and according to weight series arrangement from high to low.

The commodity classification querying server of step 708, rear end splices the commodity classification information that inquires, and returns to front-end server.

The commodity classification querying server of rear end when in queries dictionary, inquiring about according to Query Information, use be query word and the commodity classification ID that in step 705, obtains.And when the commodity classification querying server of rear end sends to front-end server with Query Result, if the commodity classification ID that directly will inquire in queries dictionary sends to front-end server, represent to the user by front-end server, then the user can't know the commodity classification of shown commodity classification ID correspondence, checks thereby can't click.Therefore, the commodity classification querying server of rear end need add the commodity classification information of the commodity classification ID correspondence that inquires in the Query Result to, or after replacing corresponding commodity classification ID, the Query Result that will comprise commodity classification information sends to front-end server, and the user is inquired about by front-end server.

Need to prove, the commodity classification information of the commodity classification ID correspondence that inquires is added in the Query Result, or the operation of replacing corresponding commodity classification ID also can be finished by front-end server.

Step 709, front-end server receive the Query Result of the commodity classification querying server transmission of rear end, screen according to Query Result.

Because log server regularly imports to the daily record that generates distributed document storage and concurrent operation platform, clicks the analytic statistics program timing stored log is carried out statistical study, the commodity classification querying server of rear end regularly loads queries dictionary.Therefore, the commodity relevant information is not real-time corresponding in the Query Result that sends of the commodity classification server of rear end and the current front-end server.For example: above-mentioned fixed cycle operator can be for once a day, and for 8:00 morning of every day operates accordingly, the user then inquires about at late 20:00.At this moment, the data of the commodity classification querying server institute foundation of rear end are the data of user inquiring 8:00 morning on the same day.If the morning of this day 8:00 between the late 20:00, the relevant information of front-end merchandise changes, for example: commodity ID changes, and makes cabinet or the like under a certain commodity class commodity now owing to substituting season, and then the user can't correctly find and want the commodity inquired about.

So front-end server need screen the Query Result that receives, the commodity classification information obtained and current all commodity classifications that meet this query word are compared.

When commodity classification that obtains and current commodity classification information conforms, front-end server shows this commodity classification information, and the DISPLAY ORDER of commodity classification from left to right is arranged in order according to the weight order from high to low of commodity classification correspondence.

When the commodity classification that obtains and current commodity classification information did not meet, front-end server shielded this commodity classification information, is not shown.

The embodiment of the present application provides a kind of querying method of vertical search, as shown in Figure 8, specifically may further comprise the steps:

Step 801, user are by the front-end server input information.

Step 802, front-end server are transmitted to commodity classification querying server with the Query Information of user's input, and commodity classification querying server is inquired about according to this Query Information.

Wherein, front-end server is transmitted to commodity classification querying server with the Query Information of user input and may further comprise the steps:
