Abstract
Searching of objects captured by a capture system can be improved by eliminating irrelevant objects from a query. In one embodiment, the present invention includes receiving such a query for objects captured by a capture system, the query including at least one search term. This search term is then hashed to a term bit position using a hash function. Then objects can be eliminated if, in a word index associated with the object, the term bit position is not set.
