What improves writing efficiency ", server is 0.5 second by the retrieval time that canonical searching algorithm is retrieved, and server is according to machine
The retrieval time that study searching algorithm is retrieved is 1 second, then server is using canonical searching algorithm as the first searching algorithm.
Server determines the second searching algorithm according to account identification, that is, sets in server previously according to history retrieval record
The corresponding searching algorithm of different Account Types is set, the account is obtained in server and identifies corresponding Account Type, then obtaining should
The corresponding searching algorithm of Account Type is as the second searching algorithm；For example, account identification is xxx, corresponding Account Type is two
Grade Account Type, server obtain the corresponding machine learning searching algorithm of secondary account type, and server retrieves machine learning
Algorithm is as the second searching algorithm.
After server determines the first searching algorithm and the second searching algorithm, server judges the first searching algorithm and
Whether two searching algorithms are identical, and when the first searching algorithm is identical as the second searching algorithm, server is directly retrieved,
When one searching algorithm and the second searching algorithm difference, server obtains corresponding first priority of the first searching algorithm and second
Corresponding second priority of searching algorithm, if the first priority is higher than the second priority, server makees the first searching algorithm
It is on the contrary for target retrieval algorithm.
It should be added that the priority of searching algorithm, can be it is pre-set, can also be according to application scenarios
It is specific to be arranged, it is not construed as limiting in the present embodiment.
Step S30 carries out information retrieval according to the retrieval information and the target retrieval algorithm, obtains and the retrieval
First search result of information matches.
After server determines target retrieval algorithm, server according to target searching algorithm processing retrieval information, and obtain
First search result obtains for example, according to target the segmentation methods in searching algorithm carry out word segmentation processing to retrieval information to server
Retrieve the corresponding keyword set of information；Then, (presetting database refers to pre-set packet to server inquiry presetting database

The flexibility and accuracy of information retrieval, meets the individual demand of information retrieval.
Further, on the basis of first embodiment of the invention, propose that the present invention is based on the inspections of the information of search engine
The second embodiment of Suo Fangfa.
The present embodiment is the refinement of step S20 in first embodiment, and a kind of configuration target is specifically illustrated in the present embodiment
The scheme of searching algorithm, the information retrieval method based on search engine include:
Step S21 obtains the information type of the retrieval information, inquires preset algorithm recommendation tables, obtain the info class
Corresponding first searching algorithm of type.
Server obtains the information type of retrieval information, and information type refers to retrieval information by information attribute, information
The information category that appearance or information function etc. are classified, for example, server can be divided by the information content by information is retrieved
Are as follows: type of message, data type and knowledge type.Then, server inquires preset algorithm recommendation tables, obtains preset algorithm and recommends
Corresponding first searching algorithm of information type in table.
Preset algorithm recommendation tables refer to pre-set information type and searching algorithm mapping table, for example, server according to
History retrieval record statistics obtains: the highest algorithm of retrieval information retrieval accuracy rate of data type is canonical matching algorithm, then
The retrieval information of data type and canonical matching algorithm are established into mapping relations in preset algorithm recommendation tables；For another example, server
Retrieve record statistics according to history to obtain: the highest algorithm of retrieval information retrieval accuracy rate of type of message is machine learning retrieval
The retrieval information of type of message and machine learning searching algorithm are then established mapping relations in preset algorithm recommendation tables by algorithm.
Step S22 obtains the history scoring of the corresponding each default searching algorithm of the account identification, and most by history scoring
High default searching algorithm is as the second searching algorithm.
Server obtains the history scoring of the corresponding each default searching algorithm of account identification, that is, presets in server
There are multiple searching algorithms, e.g., canonical matching algorithm and machine learning searching algorithm etc., it is king xx that server, which obtains account identification,
Corresponding: the historical assessment of canonical matching algorithm is 8 points, the scoring of the history of machine learning searching algorithm is 6 points, and server will just
Then matching algorithm is as the second searching algorithm.
It is to be understood that identical default searching algorithm might not in the different corresponding history scorings of account identification
It is identical, that is, the history scoring of default searching algorithm is obtained according to the history of user retrieval record: for example, setting in server
Searching algorithm p (canonical searching algorithm) and default searching algorithm q (machine learning searching algorithm), account mark are preset in being equipped with
1 has 3 history retrieval records:
The search result that searching algorithm p output is preset in first time history retrieval record is ordered as A1 and A2；Default retrieval
The search result of algorithm q output is ordered as A2 and A1；It is A1 that user, which really hits information,；Then server is by default searching algorithm p
History scoring be updated to 0+1, it is 0 that the scoring of default searching algorithm q, which is remained unchanged,；
The search result that searching algorithm p output is preset in second of history retrieval record is ordered as B1 and B2；Default retrieval
The search result of algorithm q output is ordered as B2 and B1；It is B2 that user, which really hits information,；Then server is by default searching algorithm p
History scoring to remain unchanged be 1, the history scoring of default searching algorithm q is updated to 0+1；
The search result that searching algorithm p output is preset in third time history retrieval record is ordered as C1 and C2；Default retrieval
The search result of algorithm q output is ordered as C2 and C1；It is C1 that user, which really hits information,；Server is by default searching algorithm p's
History scoring is updated to 1+1=2, and it is 1 that the history scoring of default searching algorithm q, which is remained unchanged,；Server is retrieved according to history
Record determines that the history scoring of default searching algorithm p is 2 points, and presetting the scoring of searching algorithm q history is 1 point.Server will be preset
The target retrieval algorithm that searching algorithm p is used as.
After server determines the first searching algorithm and the second searching algorithm, server judges the first searching algorithm and the
Whether two searching algorithms are identical, and when the first searching algorithm is identical with the second searching algorithm, server is by determining searching algorithm
It is retrieved.
Step S23, when first searching algorithm is with the second searching algorithm difference, by first searching algorithm
Target retrieval algorithm corresponding with information retrieval requests described in the high conduct of priority in the second searching algorithm.
When server determines the first searching algorithm and the second searching algorithm difference, server obtains the first searching algorithm
Second priority of the first priority and the second searching algorithm, wherein the priority of searching algorithm, can be it is pre-set,
It can also be server according to retrieval scene flexible setting；Then, server compares the first priority and the second priority, clothes
Business device calculates the corresponding target retrieval of the high conduct information retrieval requests of priority in the first searching algorithm and the second searching algorithm
Method.
Server configures target retrieval algorithm according to retrieval information and account identification in the present embodiment, effectively guarantees
The flexibility of target retrieval algorithm setting, so that the searching algorithm that server is different according to unused user setting, realizes
Index, which is held up, realizes decoupling with searching algorithm.
Further, on the basis of second embodiment of the invention, propose that the present invention is based on the inspections of the information of search engine
