Search Engine Server Free

Features

• Intranet searching
• ht://Dig has the ability to search through many servers on a network by acting as a WWW browser.
• It is free
• The whole system is released under the GNU General Public License
• Robot exclusion is supported
• The Standard for Robot Exclusion is supported by ht://Dig.
• Boolean expression searching
• Searches can be arbitrarily complex using boolean expressions.
• Configurable search results
• The output of a search can easily be tailored to your needs by means of providing HTML templates.
• Fuzzy searching
• Searches can be performed using various configurable algorithms. Currently the following algorithms are supported (in any combination):
• exact
• soundex
• metaphone
• common word endings (stemming)
• synonyms
• accent stripping
• substring and prefix
• Searching of HTML and text files
• Both HTML documents and plain text files can be searched. Searching of other file types will be supported in future versions.
• Keywords can be added to HTML documents
• Any number of keywords can be added to HTML documents which will not show up when the document is viewed. This is used to make a document more like to be found and also to make it appear higher in the list of matches.
• Email notification of expired documents
• Special meta information can be added to HTML documents which can be used to notify the maintainer of those documents at a certain time. It is handy to get reminded when to remove the "New" images from a certain page, for example.
• A Protected server can be indexed
• ht://Dig can be told to use a specific username and password when it retrieves documents. This can be used to index a server or parts of a server that are protected by a username and password.
• Searches on subsections of the database
• It is easy to set up a search which only returns documents whose URL matches a certain pattern. This becomes very useful for people who want to make their own data searchable without having to use a separate search engine or database.

The ht://Dig system is a complete world wide web indexing and searching system for a domain or intranet. This system is not meant to replace the need for powerful internet-wide search systems like Lycos, Infoseek, Google 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 easily span several web servers. The type of these different web servers doesn't matter as long as they understand common protocols like HTTP. ht://Dig was developed under Unix using C++. For this reason, users will need a Unix machine, a C compiler and a C++ compiler. (The C compiler is needed to compile some of the GNU libraries). Unfortunately the developers only have access to a couple of different Unix machines. Most development is done on Linux systems with gcc/g++, but ht://Dig has been tested.

ht://Dig requires a configuration file and several HTML files to operate correctly. Fortunately, when ht://Dig is installed, a very reasonable configuration is created and in most cases only minor modifications to the files are necessary. The ht://Dig package can be built on the Win32 platform when using the Cygwin package. The ht://Dig project currently uses SourceForge for a mirror of the main website at htdig.sourceforge.net as well as a mirror of ht://Dig releases and contributed work. All ht://Dig programs feature a -v option to get some debugging output. The more of these options users put on the command line, the more output users will usually get.
