SEARCH SYSTEM AND SEARCH METHOD

摘要

A search system using a table search server and a file search server as transmission destination candidates for search queries, wherein search speed is assumed to be higher for a search in the form of file data than for table data, the table data is converted to file data and stored in the file search server. Created are a search query history management table for accumulating and depositing search query history, and a characteristic determination rule management table for managing the rules of determining that the search speed is higher for a search made in the form of file data than for table data. The search system applies the characteristic determination rules to the search query history and specifies the table data. The search system acquires the specified table data from the table search server, converts the data to file data, and stores the data in the file search server.

1. A search system including a table search unit for searching for data in a table format and a file search unit for searching parallelly for data in a plurality of file formats, comprising:
a table data memory area which stores target table format data to be searched by the table search unit; a file data memory area which stores target file format data to be searched by the file search unit; a performance determination unit which specifies a part of the table format data, in unit of rows, which is recognized to be searched at a high speed when it is searched as file format data, when the table search unit searches for the table format data; a data movement unit which stores the specified part of the table format data in the unit of rows in a file, and moves it to the file data memory area; and an integrated search unit which distributes a received search query to the table search unit and the file search unit.
