Retrieval method and retrieval device

Abstract

The invention discloses a retrieval method and a retrieval device which are used for achieving very complex checking, counting and analysis functions. The retrieval method comprises the following steps: receiving a composite checking sentence input by a user, wherein the composite checking sentence comprises at least two sentences which are connected in series by virtue of a preset symbol, and the preset symbol is used for indicating to use the processing result of a sentence on one side of the preset symbol as the input of a sentence on the other side of the preset symbol; performing corresponding operation on a retrieval file or a databank by using the composite checking sentence, thereby obtaining the retrieval result. By receiving the composite checking sentence input by the user and analyzing and calculating the composite checking sentence, the final retrieval result is obtained, the user can achieve complex checking and statistic analysis by only inputting the checking sentences into a search box, a great deal of time and labor resources are saved, and very complex checking, counting and analysis functions are achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a retrieval method and device. Background technique [0002] With the continuous improvement of information construction, the use of information systems or information platforms in daily life is becoming more and more concentrated, especially to record complete operation information and processes through information systems or information platforms. At present, log information is usually used To record the operation information and process, the log is the factual data of user behavior, which can record all business data. When the user needs to query data, it can be done through the search engine of the log information, that is, the search engine is used to perform full-text indexing of the data in the database, so as to facilitate the query. Statistics and visualization of data information based on query results are not only conducive to reducing the cost of information use...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, keyword retrieval, phrase retrieval, wildcard (*) retrieval, simple regular expression retrieval, or the use of basic logic operators such as AND, OR, NOT to connect multiple query phrases are generally used for retrieval. The keywords entered in these search methods are relatively simple, so they cannot be used to query more complex query statements or situations with nested queries

Moreover, due to the full-text indexing of the data, the retrieval speed is slow and the server resources that need to be consumed are relatively large

In addition, although there are relatively rich SQL syntax for querying the log information database, these syntaxes cannot be used in the search box, which is very inconvenient for users to use
