摘要:
A system, method and computer program product for a search engine utilizing a large number of key words or phrases, and having the search engine program, in an initial search, individually search each of the key words through an initial database. Documents found as a result of each individual key word search are placed in a smaller more relevant database, after eliminating duplicate documents. Each document will contain at least one of the key words being searched. In a secondary search the remainder of the key words are searched through each document in the smaller more relevant database. The search engine notes the occurrence of any key word in each document without regard to frequency of occurrence. A relevancy factor for each document is determined based on the percentage of the total individual key words, disregarding frequency, that appear in each document. The cumulative total of key word appearances for all key words in each document is then determined. A ranking number is calculated as the product of each documents total cumulative key word count and its relevancy factor. The results progressing from highest to lowest ranking number are returned to the searcher.
