Embodiment 1
[0053] Embodiment 1 of the present application provides a method for information search, such as image 3 As shown, the information search method in the first embodiment includes the following steps:
[0054] Step 101: the merging server receives a search request sent by a user, and the search request includes keywords and search conditions.
[0055] Step 102: the merge server searches Memcached as the first-level cache, and judges whether the search result can be hit, and if so, returns the search result to the user and ends the information search process; otherwise, executes step 103.
[0056] Step 103: The merging server selects search servers for each subset of the search server set.
[0057] The specific operation of this step is as follows:
[0058] First, the merging server performs calculations on the keywords according to the set algorithm to obtain the calculation results of the keywords;
[0059] Then, the merging server selects the search server corresponding to...
Embodiment 2
[0067] Assume that in the solution of Embodiment 2 of the present application, before time T1, neither the first-level cache nor the second-level cache has a document list corresponding to the cache keyword "computer bag". At time T1, the keyword in the search request _1 initiated by user A is "computer bag", and the search condition is "price range 50 yuan to 100 yuan". At the next time T2, the key word in the search request _2 initiated by user B The word is "computer bag", and the search condition is "red".
[0068] The method for information search in Embodiment 2 of the present application includes the following steps:
[0069] Step 1: The merge server receives the search request_1 sent by user A, and the search request_1 includes the keyword "computer bag" and the search condition "price range 50 yuan to 100 yuan".
[0070] Step 2: The merging server extracts the keyword "computer bag" from the search request_1.
[0071] In this step, since the user usually URL-encodes...
Embodiment 3
[0114] Embodiment 3 of the present application provides an information search device applied in a search cluster system, such as Figure 4 As shown, it includes a request receiving module 11, an operation module 12, a selection module 13, a sending module 14 and a result receiving module 15, wherein: the request receiving module 11 is used to receive a search request comprising keywords and search conditions; the operation module 12 is used to When the search result corresponding to the search request is not found in the first-level cache, the keyword is calculated according to the set algorithm to obtain the calculation result; the selection module 13 is used to obtain the calculation result according to the calculation result and each search server in the subset. Correspondence, from each subset of the search server set, the search server corresponding to the calculation result obtained respectively; the sending module 14 is used to send the search request to the selected sea...
