htdig
\"WWW search system for an intranet or small internet The ht://Dig system is a complete world wide web indexing and searching system for a small domain or intranet. This system is not meant to replace the need for powerful internet-wide search systems like Lycos, Infoseek, Webcrawler and AltaVista. Instead it is meant to cover the search needs for a single company, campus, or even a particular sub section of a web site. As opposed to some WAIS-based or web-server based search engines, ht://Dig can span several web servers at a site. The type of these different web servers doesn't matter as long as they understand the HTTP 1.0 protocol. Features: * Intranet searching * It is free * Robot exclusion is supported * Boolean expression searching * Configurable search results * Fuzzy searching * Searching of HTML and text files * Keywords can be added to HTML documents * Email notification of expired documents * A Protected server can be indexed * Searches on subsections of the database * Full source code included * The depth of the search can be limited * Full support for the ISO-Latin-1 character set\"
Current version: 3.2.0b6
