Problems solved by technology

[0002] The application of public security information in intelligence is mainly based on the real-time analysis and processing of big data. At present, most public security systems still use traditional databases that reside on disk. With the growth of data and large-scale applications, traditional databases have reached The bottleneck of maintaining the efficient operation of the system. In the case of limited server configuration, the Oracle database has low retrieval efficiency among billions of data volumes; data maintenance is difficult and complicated. When data fields change, the original relationship code between data and data cannot Applicable, need to readjust the code, high cost, and not conducive to maintenance

Embodiment 1

[0039] The full-text index of the Migo search engine is based on the word list for word segmentation. There are currently 80 million words in the word list, including the national directory, address database, common words and all Chinese characters, etc. During the index building process, the key-value format is used to store the word and row ID sets respectively. Because the row ID set (Value) takes up a lot of space, the content of Value is stored in the disk, and only the anchor point information is stored in Value. The anchor point information identifies the start position and end position of the ID set, thus greatly saving memory space. First, The system will judge whether the retrieved keywords can be word-segmented according to the vocabulary, such as searching for "Xindehui, Zhuhai City", and judge whether the keywords can be word-segmented according to the vocabulary;

[0040] Determine whether the keyword can be divided into words: divide the word into "Zhuhai City" ...

Embodiment 2

[0055] Such as figure 1 as shown,

[0056] A search method applied to a Migo search engine, the method comprising,

[0057] In step S01, input keywords;

[0058] In step S02, perform a full-text search, determine whether the input keyword can be word-segmented, and search the separated keywords respectively, and intersect the retrieval results, and display the detailed records after the intersection,

[0059] In step S03, perform a precise search, search the input keywords, and output the search results;

[0060] In step S04, perform spatio-temporal analysis, preset the granularity of time and the breadth of space, and then analyze the peer relationship of people through the aggregation index, so as to analyze the accompanying relationship with the subject object;

[0061] In step S05, the relationship is extended to provide the function of identifying objects. When the two objects are in the same record, it is considered that the relationship can be established or the two ...

Abstract

The invention discloses a Migo search engine, which comprises an index database, a full-text search module, an accurate search module, a space-time analysis module and a relationship expansion module. The beneficial effect of the present invention is that, under the same hardware configuration, using the Migo search engine, the hardware cost is lower, the retrieval efficiency is faster, and the low-cost memory database with more efficient analysis and application is achieved.

Description

technical field [0001] The invention relates to search engine improvement, in particular to a Migo search engine. Background technique [0002] The application of public security information in intelligence is mainly based on the real-time analysis and processing of big data. At present, most public security systems still use traditional databases that reside on disk. With the growth of data and large-scale applications, traditional databases have reached The bottleneck of maintaining the efficient operation of the system. In the case of limited server configuration, the Oracle database has low retrieval efficiency among billions of data volumes; data maintenance is difficult and complicated. When data fields change, the original relationship code between data and data cannot Applicable, the code needs to be readjusted, the cost is high, and it is not conducive to maintenance. Contents of the invention [0003] The purpose of the present invention is in order to solve the...
