HouseSpider is a Java applet that adds indexing and search capability to Web sites (and to local files and CD-ROMs). It can search by two methods: by spidering through the site, or by searching a cached index file. Spider-searching is slow, but very easy to set up and requires no maintenance. Cache-searching requires only a little more attention to set up and is sometimes even faster than CGI programs. HouseSpider also supports compression of the index file and boolean searches. Translations for several languages are provided, and it can handle Web sites in any language or encoding. The applet can also run as a stand-alone application.
