Embodiment Construction
[0026] The data search system of the precision information system of the present invention is composed of two parts: the preprocessing of the search special database table and the data search of the precision information system. Taking the R&D unit as an example, the data search method and steps of the present invention are specifically described as follows:
[0027] First, establish a special database table for search (using SQLServer database)
[0028] ID
Search text
File location
Source table
Source ID
Processing date
Authority
int
btext
nvarchar
nvarchar
int
datetime
nvarchar
[0029] 1. Search dedicated database table preprocessing
[0030] The data information that needs to be retrieved is processed in advance and written into a special search database table for accurate retrieval. Search special database table processing includes two parts: existing information and new information processing. Existing information includes historical data and data processed...

The invention discloses a precise information system data searching method, composed of two parts: special searching database table preprocessing and precise information system data searching. The special searching database table preprocessing comprises: processing existing information and processing newly built information, wherein the existing information is processed by using the storage process of manually operating the special searching database table preprocessing, the newly built information is processed by using the storage process of starting the special searching database table preprocessing through a trigger; according to the special searching database table preprocessing storage process, respectively writing the retrieval text field, and the source table, the source ID and the authority field of a special searching database table to the special retrieval database table according to different texts, respectively extracting the text information in *.doc, *.pdf, *.xls files by using three sub-processes of doc2txt, pdf2tex and xls2text, thus realizing the precise information system data searching. According to the invention, the information retrieval speed, precision and security are greatly improved, and the method is the necessary retrieval method of the internal information system.
Description
Technical field [0001] The invention belongs to the field of network automation, and specifically relates to a data search method used in an internal accurate information system. Background technique [0002] Information retrieval system refers to a procedural system of information collection, processing, storage and retrieval established according to specific information needs. Its main purpose is to provide people with information services. The so-called information retrieval system refers to a collection of processed information established to meet the information needs of information users, with specific storage, retrieval and transmission technical equipment, and providing certain storage and retrieval methods and retrieval services A relatively independent service entity (including people and search units) of functions, collectively referred to as an information search system. Information retrieval refers to finding appropriate information resources or information objects ...
