Search Engine For My Site

I've moved my web site to GoDaddy. As a result, the cgi script search engine no longer works. I'd like to replace it.

I'm a pretty good VB programmer but I don't know much about ASP or PHP or any server technologies.

All I want is a text box and a button. The user enters a search term(s) and the results are displayed. The user can then click on any of the links found to go to that page.

I've looked at some PHP scripts but most of them require mySQL. My last scrip didn't use or need mySQL because the site is small - less than 150 pages right now. Each page was searched each time the search script was used.

Any ideas where I should start?
