Abstract
This invention relates to a highly efficient and user-friendly search tool for finding irregular phrases with the same attributes. User inputs a phrase or characters string on computer screen for a keyword search based on the search rules for keyword attributes. Keywords in the database sharing some common attributes are encoded, and a plurality of index tables is created on the basis of the relation of these attributes. A rapid search is accomplished through index tables by means of a reverse-exclusion algorithm, which carries out a repetitive process of rejecting those keywords in the keyword database that do not match the special attributes, until a list of relatively few keywords having the same attributes is obtained. It is then possible to perform a detailed comparison among these selected keywords to find the desired keyword.
