Swish-e

Swish-e is a fast, flexible, and free open source system for indexing collections of Web pages or other files. Swish-e is ideally suited for collections of a million documents or smaller. Using the GNOME libxml2 parser and a collection of filters, Swish-e can index plain text, e-mail, PDF, HTML, XML, Microsoft Word/PowerPoint/Excel and just about any file that can be converted to XML or HTML text. Swish-e is also often used to supplement databases like the MySQL® DBMS for very fast full-text searching.
