ABSTRACT:
Disclosed herein is a computer implemented method and system that progressively relaxes search terms provided by a user. Data of predefined types is stored in a database. The data is obtained by uniquely modifying data previously stored in the database, based on the predefined types. Search terms of predefined types are accepted from the user. The search terms are compared with the stored data to find exact matches, if length of the search terms exceeds a predefined value. On not finding exact matches, the accepted search terms are modified uniquely based on the predefined types to structure first alternative queries. The first alternative queries are compared with the stored data to find exact matches. On not finding exact matches, the first alternative queries are modified based on the predefined types to structure second alternative queries. The second alternative queries are compared with the stored data to find approximate matches.
