Yahoo is bolstering its search offering with Search Pad, a tool that detects when users have begun in-depth research and which offers them the chance to keep track of their results.

Yahoo Search Pad keeps track of search terms used, and when it detects a trend it offers to save the results in an online document.
If the option is selected, the service shows the user a page of websites they have already visited on the subject.
Users can annotate results and delete pages they do not like. They can also add website pages they have found through different search engines.
Yahoo is publicly testing Search Pad among a small number of randomly selected users.
The service should be available to all users later this year, according to Yahoo.
