Boolean Search for Mac

Boolean Search is a Mac OS X web server application for searching the contents of files. Boolean Search can be employed as a search engine for a public website on the Internet, or a personal or group owned collection of files on your own computer or network. A wide variety of search criteria and customizable response pages makes Boolean Search a very flexible alternative to Internet search engines or operating system services like Spotlight.

Search forms and results are highly customizable with the use of "templates," standard HTML and AppleScript.

Generation of a "site index" which lists all the words contained in a file collection, and links to the files which contain them.

Various query-based search methods are available: exact, partial, approximate, case sensitive, proximity, phrase, regular expression pattern matching, etc.

A wide variety of "context summaries" of found documents are available, and files are viewable with search terms linked and highlighted.
