Applets
These applets let you set up searching for sites that can't host CGI scripts (there are also Java search servers). They generally do a site crawl from a root page (usually your home page). Some include source code.
- ClientSearch - Free under the GNU Copy-left. The examples didn't work for me (Netscape 4.05 on the Mac)
- Babbage Home Page Search Applet - Free under the GNU Copy-left The example worked fine for me, though the interface was a bit primitive. This does not keep an index, so it works on hosted sites, but it's very slow.
