Recoll is a personal full text search package with a QT graphical
interface. It is based on a very strong backend (Xapian), for which it
provides an easy to use and feature-rich interface.

    * Supports the following document types (and their compressed versions): 
      - Natively: text, html, OpenOffice files, maildir and mailbox
