This plugin is used to collect the query string from Google, Bing and Yahoo. It lists the last 5 as a sidebar widget so that users might click on them and find information using the WordPress search.
In this way a user might find more pages that satisfy his search and other users may be interested in the same things that previous searchers used as queries.
It is quite possible that the Search engine query will result in a not found because the wordpress built-in search is not very flexible.
Requires WordPress Version: 2.0 or higher
