Recoll is a personal full text search tool for Unix/Linux. It is based on the very strong Xapian backend, for which it provides an easy to use, feature-rich, easy administration, QT graphical interface. Recoll is able to include several separate folders ("Top directories") in its search. This requires xapian-core, with optional dependencies of antiword, unrtf, and exiftool (all available at SlackBuilds.org).
