Embodiment Construction

[0033] A kind of data inquiry method of the present invention, refer to figure 1 As shown, it mainly includes the following steps:

[0034] Step 101: storing each data in the form of a file;

[0035] Step 102: generating an index table of the file;

[0036] Step 103: According to the index table, complete the query for the data to be queried.

[0037] Wherein, in step 101, each data is stored in the form of a file, refer to figure 2 As shown, it specifically includes the following steps:

[0038] Step 201: Parse the original data from the data carrier, and obtain the attribute fields of each original data and the field values ​​of each attribute field;

[0039] Here, the data carrier includes, but is not limited to, network data packets, data files, database tables, and the like.

[0040] Specifically, for different data carriers, the acquired original data needs to be parsed according to their corresponding decoding methods.

[0041] Assuming that the data carrier is a...

Abstract

The invention discloses a data query method, a data query device and a data query system. The data query method comprises the following steps: storing original data acquired from a data carrier in the form of file; generating an index table for each file; and during query, firstly querying the index table of each file according to a key word in a query request and finding data to be queried in each file according to the queried index table. The invention further discloses the data query device and the data query system. The method, the device and the system solve the problems that the hit rate of index query in WEB search is low and indexes cannot be used for fuzzy query in database query, and can effectively improve the accuracy and efficiency of data query, achieve 100 percent hit, realize the quick indexing and quick query of a vast amount of data and ensure relatively higher query accuracy in the query of the vast amount of data.

Description

technical field [0001] The invention relates to the field of information retrieval, in particular to a data query method, device and system. Background technique [0002] WEB search engine is a common search engine for massive data. It generates index information by full-text indexing the information that users care about, such as title, webpage URL, text, etc.; when querying, search index information, quickly locate the webpage, and then display the webpage to the user. Since the retrieved information in WEB search is pre-indexed, the query only needs to query the index without rescanning all the content, so the query efficiency is very high. [0003] Since the processing object in WEB search is text, more attention should be paid to word segmentation, indexing and storage of specific languages. For example, when querying the IP of A.B.C.D, the WEB search process will segment and index the IP according to the four data of A, B, C, and D, rather than the IP itself. Therefo...
