</VirtualRegisterDescription>
Wherein, virtual register documents can comprise a plurality of search engine information that can virtual registration.ShortName represents the sign of search engine, and MetaSearchID represents the search server under the search engine, and Tags represents search-type, represents the searching request interface with the Url query template.
202, obtain the Qu Peidu of each search engine of local registration to this searching request.
Described district degree of joining is meant the similarity of the Query Result of search engine for given inquiry (also being search condition), and its similarity size can be similar to the relevant useful degree size with search engine of the described given inquiry of reflection.In general, for given inquiry, Qu Peidu is high more, and then the Query Result of search engine is correct more.
Search server extracts search condition from searching request, described search condition can be a searching key word, also can be SQL (Structured Query Language Structured Query Language (SQL)) statement.Take out the search engine of all registrations from local registration center and tabulate, according to the Qu Peidu of first index calculation search engine search condition.
Search server can sort from high to low to the Qu Peidu of its search engine of managing, if there be the search engine of Qu Peidu greater than predefined threshold T, then can think and find search effect search engine preferably, the selection flow process of this search engine finishes.Search server can utilize these district's degree of joining to search for greater than the search engine of predetermined threshold value T.When if there is not Qu Peidu greater than the search engine of described predefined limit value T in search server, then continue execution in step 203, certainly search server also can be when finding Qu Peidu greater than the search engine of predetermined threshold value T, still continue execution in step 203, in the hope of from the search engine of the virtual registration of search server, finding the search engine of search better effects if.Predefined threshold T can be that its each search engine unification of managing is set for search server, each search engine can have the threshold T of a correspondence in addition, threshold value such as search engine Ei correspondence is Ti, if district degree of the joining Ri of Ei is greater than Ti, think that then the search effect of Ei is better, this situation also can be thought and found search effect search engine preferably.Wherein, Ti can be preestablished by search server, also can provide for search engine oneself.
203, obtain at the identification information of the search engine of the virtual registration of this search server and the identification information of affiliated search server thereof.
According to the identification information of the search engine that is obtained and the identification information of affiliated search server thereof, search server can be determined search engine and affiliated search server thereof.This step is divided following two kinds of situations:
1, comprise search-type in the searching request
Search server extracts from searching request wants search-type, and virtual registration center finds the one or more search engines that belong to this search-type.From searching request, extract the ground domain information that to search for then,, then obtain the identification information of these search engines and the identification information of affiliated search server thereof if do not comprise the ground domain information in the searching request.
If comprise the ground domain information in the described searching request, then from the above-mentioned search engine that finds, the scope of finding out service contains the search engine of described ground domain information.Such as, if the ground domain information is the Shenzhen, then select service range to comprise the search engine of Shenzhen.Obtain the identification information of these search engines and the identification information of affiliated search server thereof then.
2, only comprise searching key word q in the searching request, do not comprise search-type.At this moment, following three kinds of schemes can be arranged:
One, virtual registration center can determine the default search type of searching request.And then determine to belong to the search engine of this default search type, obtain identification information at the identification information of the search engine that belongs to this default search type of the virtual registration of this search server and affiliated search server thereof.Described default search type is preestablished by search server.
Two, from described searching request, extract the ground domain information that to search for,, then obtain identification information at the identification information of all search engines of virtual registration center registration and affiliated search server if do not comprise the ground domain information in the searching request.If comprise the ground domain information in the described searching request, then from all search engines, the scope of finding out service contains the search engine of described ground domain information.Such as, if the ground domain information is the Shenzhen, then select service range to comprise the search engine of Shenzhen.Obtain identification information at the identification information of all search engines of virtual registration center registration and affiliated search server.
Three, set up dictionary for search-type, searching request and dictionary are mated, determine type under the searching request according to matching result, and then determine to belong to the search engine of this default search type, obtain identification information at the identification information of the search engine that belongs to this search-type of the virtual registration of this search server and affiliated search server thereof.。During specific implementation, described searching request and dictionary mate and are: from described searching request, extract searching key word, according to described keyword determine to pre-set to search-type that should keyword.In a concrete example, as shown in Table 2, in the dictionary of search-type, each search-type is made up of a lot of keywords.From searching request, extract searching request keyword q, q is cut speech, as be cut into that { key1, key2} is then { key1, key2} and dictionary mate.The search-type that finds searching request q to belong to by coupling.
Table two:
| Search-type 1 | Search-type 1 | Search-type 1 |
| ??Keyword1 | ??Keyword3 | ??Keyword5 |
| ??Keyword2 | ??Keyword4 | ??Keyword6 |
204, identification information visit and corresponding search server according to described search server obtain the Qu Peidu of the search engine of described the virtual registration of search server to described searching request.
Describe for the ease of clear, suppose that described search server is search server A, search server is search server B under the search engine of described the virtual registration of search server, search server A according to described under the search engine of the virtual registration of this search server search server B identification information can so that the information such as IP address of definite search server B, realization is to the visit of search server B, searching request is forwarded to this search server, and then according to identification information at the search engine of the virtual registration of this search server, obtain the Qu Peidu of this search engine by search server B, and this district's degree of joining information is returned to search server A.The specific implementation said process can comprise following two steps:
1, the search engine that virtual registration center returns is received by the virtual registration center of search server A, extracts searching key word q from searching request, then searching key word q and search engine sign is sent to search server under it.Suppose that the search engine that sends is b1, the search server under it is B.
2, after search server B received request, the first index calculation b1 by search server B was to district degree of the joining R_b1 of keyword q; And the access authorization information of district's degree of joining and search engine b1 turned back to search server A.Wherein, the access authorization information of search engine b1 is optional, also can only return the Qu Peidu value of b1 to search server A.
Described access authorization information is the access rights control information of search server to search engine, can be an authorization code.Search server A can rely on the direct access search engine of this access authorization information b1.
If search server is received a plurality of search engine information, then repeat above-mentioned two steps
205, to the search engine of the Qu Peidu of this searching request and described the virtual registration of search server Qu Peidu, determine that at least one is used for carrying out according to described searching request the search engine of information retrieval according to each search engine of described local registration to described searching request.
After search server A receives search engine district degree of the joining information and access authorization information thereof that other search servers return, the record access authorization message.And the matching degree of the search engine managed of comparison search server A and the Qu Peidu of these search engines.Compare the effective search engine of search according to the matching degree size.
The method of selecting is specifically as follows and allows the Qu Peidu of these search engines sort from high to low, selects the highest top n search engine of Qu Peidu.The value of N has search server to preestablish.
Perhaps, select the search engine of Qu Peidu greater than T2 according to the threshold value T2 that sets in advance.Threshold value T2 is preestablished by search server.
Search server A calls these search engines and searches for after selecting the one or more preferably search engines of search effect.The mode of calling the search engine that search engine that search server manages and other search servers manage is different.For the search engine that search server A is managed, search server A can directly call these search engines.The result that these search engines are returned compiles processing then.At last Search Results is returned to the user.For the search engine of other search servers, search server A can directly call, also can indirect call.Directly calling is exactly the access authorization information that search server A can utilize these search engines, directly calls these search engines.Indirect call is exactly that search server A sends to its affiliated search server to search engine sign of having selected and searching request.For example send search engine b1 and searching request q to search server B, search server B sends to search engine b1 to searching request q, b1 returns to search server B to the Search Results of q, by search server B the result of searching request q is returned to search server A.
After search engine is selected by the dispatching center of search server A, call one or more search engines.When calling a plurality of search engine, the result that these search engines are returned compiles processing, at last Search Results is returned to the user.
With reference to figure 4 are schematic flow sheets of embodiment of the invention search engine system of selection, and this method flow comprises:
301, search server A receives the searching request from the user;
302, search server A obtains the Qu Peidu of each search engine of local registration to described searching request.
This step is identical with step 202 among the preceding method embodiment, does not repeat them here.
303, search server A sends to received searching request the virtual registration center of search server A;
304, return the identification information of search engine and the identification information of affiliated search server thereof, as hypothesis according to as described in the search server identification information be defined as the search engine that search engine that search server B managed and search server C are managed.
305, transmit searching request to search server B;
306, after search server B receives searching request, go out the Qu Peidu of the search engine that described search engine identification information identified according to first index calculation;
307, return the Qu Peidu of search engine;
308, transmit searching request to search server C;
309, after search server C receives searching request, go out the Qu Peidu that described member's search causes the search engine that identification information identifies according to first index calculation;
310, return the Qu Peidu of search engine;
311, each search engine of this locality registration of obtaining in the comparison step 302 is to the Qu Peidu of described searching request, the Qu Peidu that is returned by search server B in the step 307, and the Qu Peidu that is returned by search server C in the step 310 select more excellent search engine.
With reference to figure 5, be the structural representation of embodiment of the invention search server, this search server mainly comprises:
Unit's indexing units 7 is used to generate and manage first index of the search engine that described local registering unit 5 registered;
Unit's indexing units is that the search engine registered of described local registering unit 5 generates and sets up first index, and the concrete mode of setting up first index has multiple, the concrete example of a first index as shown in Table 3.
Table three:
