GrowSearch is free to use. That doesn't mean its free, it just means we place no restriction on how you use it after you buy it as long as you adhere to the license conditions below. Although we don't offer the code for free, at £1 its pretty close and we don't try and disallow you from profitting from using it in turn. When you stack it up against the commercial site search and mapping tools available for 300 times the price, hopefully you'll agree its worth the nominal charge.

Your host needs to support PHP scripting. If they don't, ask them to install it or switch to one of the 99% of providers who do - PHP is free!
Descriptive <title>'s or <h1>'s are recommended for your site pages. It's not so much a requirement but just good practice because the search routine and site map indexes all pages and can use the contents of any tag you choose as the display text for the pages in the list.
GrowSearch was originally created for our own use (it's used in gr0w.com). We wanted a simple plug-in that made searching any kind of web page a breeze, regardless of user skill level. We also wanted a routine to produce a site map that would update automatially as part of the package. So after a fair slice of hard work allowing for the varied uses you might put it to and readying it for everyone to use its finaly here: Our combined site search and map. Enjoy! More about the work can be seen in the forthcoming library article.
I've finaly got around to writing a press release for GrowSearch. Please feel free to take peek if that kind of thing interests you.
