Abstract
In an information retrieval method a meta search engine receives a user information query in the form of key words; and submits the query to a search engine, and also submits the query to a snippet database storing previously selected results, indexed by a snippet index of terms included in snippets of the results when they were previously selected. The meta search engine then receives results from the search engine; and receives a response from the snippet database. It merges the results from the search engine with those from the snippet database; and submits re-ranked results to the user. The snippet database processes in parallel with the underlying search engine. The meta search engine also monitors which results of the returned re-ranked results are selected by the user, and updates the snippet index accordingly.
