Old user interface for Beagle, code named Best
Beagle is a search system for Linux and other Unix-like systems, enabling the user to search documents, chat logs, email and contact lists. It is not actively developed.
Beagle grew out of Dashboard, an early Mono-based application for watching and presenting useful information from a user's computer. It is written in C# using Mono and uses a port of Lucene to C# called Lucene.net as its indexer. Beagle includes a Gtk#-based user interface, and integrates with Galago for presence information.
Beagle was developed and maintained by Joe Shaw, with help from the open source community. Other notable past contributors include Jon Trowbridge, Robert Love, Nat Friedman, and David Camp.
Beagle searches the content of documents and associated metadata. With Beagle, users can search for:
- Archives (zip, tar, gzip, bzip2) and their contents
- Conversations (Pidgin, Kopete and IRC logs)
- Documents (AbiWord, OpenOffice.org, Microsoft Office, pdf, txt, rtf, html)
- Emails and Address Book contacts (from Evolution, Mozilla Thunderbird (header info only), and KMail)
- Help files (Texinfo, man pages)
- Images (png, jpg, tiff, gif, svg)
- Music files (mp3, ogg, flac)
- Notes taken in Tomboy, KNotes, and Labyrinth
- RSS feeds (via Blam or Akregator)
- Video files (through MPlayer or Totem)
- Web history (Firefox, Konqueror, Epiphany)
Beagle can also index additional file types not natively supported using external tools through a configuration file.
Beagle can efficiently index documents on Linux systems using inotify.
