Incremental search of keyword strings

摘要

An incremental keyword search may be performed by receiving an input keyword string comprising one or more words having one or more symbols, creating a bit vector based at least in part on the input keyword string, comparing the bit vector with one or more other bit vectors representing at least one candidate keyword string to create a set of matching bit vectors and applying a conventional keyword matching algorithm to the at least one candidate keyword string represented by the matching bit vectors. Any matching candidate keyword strings are presented.
