Abstract
A system and a method for searching does not rely on prior compiled vocabulary information or grammatical information to perform a search. The search may accommodate new words or phrases, and perform a document search using a request of a user for document search. A unique character string is extracted from an input document and a similarity search is performed by using the unique character string. The extraction of the unique character string is performed by calculating and evaluating an amount of feature of a character string through comparison between appearance frequency appearing in the input document and appearance frequency in a set of documents to be searched. Then, the extracted unique character string is used as the basis for the search. Documents found by the search are evaluated and arranged in the order of evaluation. The similarity factor of document is evaluated by using the appearance frequency of each unique character string in the input document so that higher evaluation is provided to a document in which unique character strings with higher weight appears many times.
