As example we write how to install using a Debian/Ubuntu system -

apt-get install tracker tracker-utils to install the indexer and the command line
apt-get install tracker tracker-utils tracker-search-tool libdeskbar-tracker to install the Gnome GUI and the deskbar handler.

Key Features

Supports both free text search (like Beagle/Google) as well as structured searches using RDF Query.
Responds in real time to filesystem changes, automaticaly keeping its metadata database up to date.
Extracts file contents as plain text and indexes them.
Can provide thumbnailing on the fly if a thumbnail does not currently exist.
Uses multilingual word stemmers to help find more relevant results. For example a search for motorbikes (plural) will also return results relevant to motorbike (singular).

Desktop Neutral Design

Adheres to freedesktop thumbail spec.
Uses freedesktop technologies like DBus and XDGMime.
Uses XDG utils like xdg-open.
Implements the freedesktop specification for metadata (http://freedesktop.org/wiki/Standards/shared-filemetadata-spec).
Supports the WC3's RDF Query syntax for querying that metadata.

Efficienct and Stable

Written in C for maximum efficiency.
Designed and built to run well on lower-memory systems with typically 128MB or 256MB memory. Typical RAM usage is 3-9 MB.
High performance indexer capable of indexing 100+ text files a second.
Scheduled nicely so that you can work and use your machine without noticing any slow downs.
Extractors run in separate processes, so a crash in one will not bring down the daemon.

Components

Indexer, a lightweight daemon that extracts information from files (trackerd).
Tracker search tool, a small GUI to search for indexed data.
Command line tools for searching, querying the daemon status, and tagging.
libtracker, a C wrapper around the DBus API.
Full DBus API for application authors using different toolkits or programming languages.

Use Cases

Application-neutral and desktop-neutral tagging. Tagging support 'for free' in any application that uses tracker, such as Nautilus and file-chooser dialogs.
A cross-application metadata database. If applications chooses to use Tracker as their metadata database and indexer, they would see signifigant improvements. Users would no longer need to add a MP3 they have downloaded to Rhythmbox, nor a photo they have taken to f-spot, these items would be detected and imported automatically.
Users may completely move away from a folder-heirarchy based home folder, and instead organise their data into collections using tags. The combination of tagging support in the file-chooser, tagging awareness in Nautilus, or even a tag based filesystem using FUSE could allow radical exploration of new desktop ideas.
Improved performance. With an always running indexer application start up time could be dramatically reduced in instances where applicaions scan or parse a numer of files on disk. For example alacarte could use tracker as its desktop file parser, or rhythmbox could use tracker as its song index. In addition by using a DBus based API one can take advantage of asynchronous replies for improved GUI responsiveness.

What is it?

Tracker is a tool designed to extract information and metadata about your personal data so that it can be searched easily and quickly.

By using Tracker, you no longer have to remember where you've left your files. To locate a file you only need to remember something about it, such as a word in the document or the artist of the song. This is because as well as searching for files in the traditional way, by name and location, Tracker searches files' contents and metadata.

Metadata, or data about data includes attributes specific to each file, such as the artist of a song or the author of a document. Tracker reads this metadata, and places it into and index, which allows searches to be lightning fast. Tracker updates its index automatically, so search results are always accurate up-to-the-moment.

Tracker doesn't stop there -- by allowing you to attach your own metadata to files it frees you from having to keep everything in highly organised folders. You can add one or many 'tags' to files, effectively grouping several files in your filesystem even if they are located in different folders. So, tagging can be much easier and more flexible than fitting your information into preconceived categories or folders.
