I have not been a huge fan of search agents or assistants. I find that they tend to slow down my computer and are headaches to maintain in order for them to work properly.
Here is a search assistant that does not involve any efforts to set up.
GoshMe is a meta tool that permits users to search among 1350 engines and databases at one time. The tool assists users to delve into the invisible web where general search engines cannot go. Users can simply enter their keyword(s) and receive hits from all search engines / sources or broken down by a specific tool (ie, video search, blog search, news search, etc.). The screenshot below presents the results for a video search for the keywords, “NCAA tournament”.

The links provided on the result pages of GoshMe lead users to the hits from a specific tool. The first hit originates from Google Video in the above screenshot.
GoshMe is available at http://www.goshme.com/. GoshMe is currently in beta testing phase.
