Step 506, the seller ID that the search of Searcher server record obtains and the corresponding relation of qualified commodity ID.
Preferably, the Searcher server merges all commodity that satisfy condition that search obtains according to the seller, and namely a seller only keeps commodity, and the seller ID that record searching obtains in seller's table and the corresponding relation of these commodity ID.
Whether step 507 has recorded the seller ID that current search obtains before the Searcher server is judged.Then to go to step 508 if be judged as; Otherwise, go to step 510.
Wherein, when the determination result is NO, illustrate that this seller does not satisfy the commodity of front condition, therefore get rid of this seller.
Before judging, step 508, Searcher server whether recorded the corresponding relation of the commodity ID that this seller ID and current search obtain.Then to go to step 510 if be judged as; Otherwise, go to step 509.
Preferably, the corresponding commodity ID of each the seller ID that searches each time, these commodity ID obtains by following manner: the Searcher server sorts to this seller's that search obtains commodity, selects the commodity ID of first commodity as the commodity ID that belongs to this seller ID.Wherein, the mode that seller's commodity are sorted comprises according to price from low to high, perhaps according to the time of making the product by as far as near etc.
Step 509, the seller ID that Searcher server record current search obtains and the corresponding relation of commodity ID.
Step 510, the Searcher server judges whether to exist not searched keyword sets.Then to go to step 504 if be judged as; Otherwise, go to step 511.
Step 511, Searcher server are obtained the quantity of commodity ID corresponding to each seller ID of record, compare the seller ID output Search Results identical according to quantity with the quantity of the keyword sets of carrying in the searching request.
The Searcher server checks seller's table, if the number of a qualified commodity ID of seller is less than the number of the keyword sets of carrying in the searching request, be the number of commodity to be searched, show that then this seller does not have the commodity that satisfy all conditions, deletes this seller's record.For qualified seller, sort according to user's specified requirements (such as total price or the prestige corresponding to seller of commodity corresponding to qualified seller), return Search Results to merger.Same seller's commodity return together.For example, if specify the total price ordering, the Searcher server will calculate the total price of qualified all commodity of each seller, according to returning merger after the total price ordering.
Step 512, merger receives the Search Results that each Searcher server sends, and Search Results is sorted, and returns net result to user side.
The user can directly buy all commodity, perhaps enters a certain shop and continues to select, and perhaps re-enters querying condition and/or sort criteria etc. and searches for.
It should be noted that, in this embodiment, in guaranteeing each seller who obtains according to each keyword sets search, only comprise under the prerequisite of commodity, the Searcher server can also directly record search obtains according to each keyword sets seller ID and the corresponding relation of commodity ID, and after all keyword sets were all searched, the commodity ID quantity seller identical with keyword sets quantity that will comprise returned as Search Results.
