Obtain the parameter preset in described URL request, described parameter preset is used for identifying user search behavior;
According to described parameter preset, judge that current retrieval request is the retrieval request of first stage or the retrieval request of subordinate phase.
Concrete, can judge according to the sc_tr parameter in URL request, when without sc_tr parameter or sc_tr=1, determine that current retrieval request is the retrieval request of first stage, or, work as sc_tr>1, determine that current retrieval request is the retrieval request of subordinate phase, in addition, can also determine which term user have selected by sc_tr parameter.
S607: the result of recalling obtained is recalled to queue and carries out merging rearrangement.
Carry out after queue recalls, the retrieval of the English query that original query and user choose all is called back, and just needs the sequence carrying out result after recalling.Can sort according to the correlativity of recalling result and original query, and stepping can be obtained to Relevance scores division.Results relevance score in same shelves be considered as the same, other factors then according to paper in current shelves sort, as quoted number of times.Quote number of times more, more show the quality of paper.
S608: according to the advanced filter information preset, be combined the result of recalling after rearrangement and screen, obtain result for retrieval.
Advanced filter information can be default, the tabulate statistics information of such as academics search result, adds up the paper publishing amount of current result for retrieval different field, time etc., and can search for click when front end represents.Such as, see any one result of page searching in Fig. 2-Fig. 4, this result of page searching can comprise " advanced filter " option, user can open this " advanced filter " option and select.See Fig. 8, after opening " advanced filter " option, be supplied to alternative content of user.
Result for retrieval due to the most multiple query merges and returns, and therefore needs the Sino-British query clicked according to user to carry out corresponding advanced filter information and merges.
The mixing of final many query result for retrieval represents the result for retrieval that effect can be shown in Figure 4.
S609: show result for retrieval and associative search word.
By Chinese and English query conversion above and query mass filter, can obtain the Chinese and English query combination being presented to user in front end, user can according to the intention demand of oneself, and single choice or multiselect need the Chinese and English term carrying out searching for.
If the term of initial acquisition is the term of first stage, then now show the result for retrieval that the term of first stage is corresponding, such as, the result for retrieval of corresponding Chinese retrieval word as shown in Figure 2.Or, if the term of initial acquisition is the term of subordinate phase, then now show the result for retrieval that the term of subordinate phase is corresponding, such as, the result for retrieval of the pure English term of correspondence as shown in Figure 3, or, the result for retrieval of Chinese and English mixing as shown in Figure 4.
S610: judge whether user have selected associative search word, if so, repeat S601 and subsequent step thereof, otherwise, perform S611.
Such as, can judge to have selected term according to user's check boxes whether clicked before associative search word.
S611: terminate.
