Abstract
A method and system for generating and searching a full text index. The fill text index includes the use of word numbers and a minimum delta which minimizes the need to access document level information during the application of search operators. Word registers having coordinated document level and word level information, as well as relevance information are used in search operations. Word numbers are clustered together during sub-operations in preparation for the next operation in a search query. The fill text index according to the present invention is extremely efficient and greatly reduces table accesses and/or disk I/Os.
