Problems solved by technology

In traditional search, we will face two problems. One is that the total amount of data is too large, the search speed is slow, and frequent searches affect server performance. The other is that the query conditions are relatively fixed and cannot be flexibly configured

Embodiment Construction

[0040] figure 1 It is a schematic diagram of the secondary retrieval process. It includes client, WEB server, application support, middleware, middle library, Solr server and business database, and the present invention realizes the secondary fast retrieval function of large amount of data.

[0041] The business process of its secondary retrieval is as follows:

[0042](1) When the web server requests a query, it queries the business database, returns the inspection result set and displays it on the page, and creates an index file through the solr server (the solr server reads the index template index.xml and extracts all data that can be used as query conditions Items and splitting rules, and check whether the data item is within the scope of a query. If so, create an index. The index contains fields that can be used as query conditions and field splitting rules. For example, if IP is used as a query condition, the index will record IP mark bit, and create an index with IP...

Abstract

The invention discloses a data query method and a data query system based on quadratic search. The data query method comprises the following steps: (1) establishing an index template, when a user logs in a client for the first time of search, generating a bath number for the logging of the user, and storing the batch number and the first time of retrieved result in a middle base server; (2) an index server extracting all data items and splitting rules capable of serving as query conditions from the first time of retrieved result according to an index template, and establishing the index of the batch number; (3) when the user carries out quadratic search, reading all index data containing the conditions of the quadratic search input by the user from the index of the batch number, and then obtaining the retrieved result from the middle base server according to the index data. The query conditions of the quadratic search can be dynamically reconstructed, and the result of one-time query is cached through a middle base, so that the total data volume during the quadratic search is reduced, and the efficiency of quadratic search data is greatly improved.

Description

technical field [0001] The invention relates to the field of Internet search, in particular to a data query method and system based on secondary retrieval in search. technical background [0002] With the rapid growth of the Internet, people's mining and application of massive data heralds the arrival of a new wave of productivity and consumer surplus. Big data has begun to attract people's attention, and its data volume far exceeds the current enterprise IT architecture and infrastructure. The carrying capacity and real-time requirements of facilities will also greatly exceed the current computing power. How to retrieve valuable data from big data and provide assistance for national governance, corporate decision-making and even personal life services has become an issue for people. [0003] People are increasingly relying on search engines to obtain valuable data. Through keyword searches, a large amount of result data can be returned, but most of the data is not within th...
