Embodiment 1

[0032] A high-efficiency search method based on big data. According to a new query request from a user, the method first judges whether there is a precedent for the query or a part of the query in the historical record, and if so, shares the result set of the historical query to Reduce the time consumption caused by re-running all queries against large data collections.

Embodiment 2

[0034] On the basis of embodiment 1, the implementation steps of the method described in this embodiment are as follows:

[0035] Step 1: The user first puts forward a new query request;

[0036] Step 2: Match the new query request from the user with the historical query network,

[0037] Step 3: Feedback the results required by the user's query to the user;

[0038] Step 4: Realize the updating of the history query network.

Embodiment 3

[0040] Such as figure 1 As shown, on the basis of Embodiment 2, the matching described in this embodiment has the following three situations:

[0041] 1) Full sharing: If it is fully shared, it means that the user's new query request has also appeared before, so that the query results obtained by the same previous query can be directly used for this query;

[0042] It needs to perform the following processing:

[0043] a. Share the query results of the same query in history;

[0044] b. Since the historical query is only a query of the data before a certain period of time, there may be new data records generated after the historical query, so it is still necessary to query the newly added data and obtain relevant results;

[0045] c. Merge the results of a and b to obtain the final result required by the user;

[0046] 2) Partial sharing: if it is partial sharing, it means that the user's new query request has appeared in part before, so that the query results obtained from...

Abstract

The invention discloses a big data based efficient search method. The method comprises the steps of determining whether a case for the querying or partial querying is in the historical record according to the new querying requirement from a user; if so, sharing the result set of the historical querying. The method can solve the problem of small search efficiency of the big data, reduce a large number of repeated calculation for the historical querying, save the search time and increase the search efficiency.

Description

technical field [0001] The invention relates to the field of computer big data, in particular to an efficient search method based on big data. Background technique [0002] With the rapid development of cloud computing technology, especially the development of Internet of Things technology and mobile technology, more and more data are generated by people, various sensing devices or machines. More and more applications generate terabytes or even petabytes of data every month. At the same time, more and more applications need to process tens of petabytes, hundreds of petabytes or even exabytes of data every day. [0003] Although there are many new technologies or methods for big data processing, it still takes a long time to extract a record or a suitable webpage that meets the user's query requirements from PB-level big data. Queries, especially real-time queries, are still a huge challenge. [0004] Although various search methods have appeared, it is still difficult to m...
