Yahoo! provides a tool that allows WebHosting members to search for content on their own web site. You can see an example of it in action on the home page of this web site. (Use the "Show Me How" link on the home page to see the code.)

You don't have much control over which files on your web site are included in the search so, if you have content that you don't want everyone to be able to find, you may not want to set up a public page with the personal site search code. You still may want to set up such a page in a password-controlled directory so you can use it yourself.
