Classification: CPC G  H | IPC G  H

Claim 0:
1. A hash code-based search apparatus comprising:
a token set extracting unit configured to extract a token set having at least one token from a document;
a hash code generating unit configured to generate N hash codes by applying N hash functions to the at least one token, N being a natural number; and
an index generating unit configured to generate a search index by indexing the document with the N hash codes,
wherein the hash code generating unit is further configured to
determine the N hash functions and generate one hash code by applying one of the N hash functions to the at least one token, and
select the N hash functions from a population of hash functions based on a size of a hash code output from each of the hash functions and a type of the document, and

wherein the token set extracting unit, the hash code generating unit, and the index generating unit are each implemented via at least one processor.
