You can find the bookmarklets on the following website:

Update: The original website is no longer available on the Internet. You find an alternative over at the Squarefree website which offers a collection of search related bookmarklets.

Another promising site with a great collection of bookmarklets is Marklets. The site offers a huge collection of bookmarklets for all kinds of purposes.

File search recently has come under scrutiny though as search engines like Google began to remove results from file hosting and sharing sites such as Rapidshare from their index. If you search for Rapidshare files on Google you will end up with a few dozen results tops.

Most users therefor may want to use special websites that index files that are hosted publicly on the Internet instead of bookmarklets.

You can also visit this site that offers a bookmarklet to search the active site. You could use it to search your favorite file hosting site or download site right away without having to go to a search engine’s site first or using the internal search of the service.

Just bookmark the bookmarklets and execute them whenever you need to access them. Executing means clicking on them when you are on the site you want to use them one.
