Search query processing to identify related search terms and to correct misspellings of search terms
First Claim
1. A method of processing search query submissions, the method comprising:
- programmatically analyzing search query submissions of a plurality of search engine users to identify search terms that co-occur within search query submissions relatively frequently; and
generating, within computer storage, a table reflective of a result of the programmatic analysis of search query submissions, said table identifying specific search terms that are related to each other.

Abstract
A search engine process predicts the correct spellings of search terms within multiple-term search queries. In one embodiment, when a user submits a multiple-term search query that includes a non-matching term and at least one matching term, a table is accessed to look up a set of terms that are “related” to the matching term or terms. A spelling comparison function is then used to determine whether any of these related terms is sufficiently similar in spelling to the non-matching term to be deemed a candidate correctly-spelled replacement. A candidate replacement term may automatically be substituted for the non-matching term, or may be suggested to the user as a replacement. The invention also includes a process for identifying terms that are related to each other based on the relatively high frequencies with which they co-occur in search queries of users, database records, and/or specific database fields.
