Unlike some other indexers, Tracker is designed and built - to run well on systems with lower memory (256MB or less). It - should even be efficient enough to use on some mobile devices. - - * Non-bloated and written in C for maximum efficiency. - - * Small size and minimal dependencies makes it easy to bundle - into various distros, including live cds. - - * Fast indexing and unobtrusive - no need to index stuff - overnight. Tracker runs at nice+10 so it should have a minimal - impact on your system. With the addition of detection of mouse - and keyboard events via tracker-applet (described below), there - is an option to auto-pause indexing in order to improve - responsiveness. This is in addition to Tracker's built-in check - if there's heavy disk I/O in order to auto-pause, so not to - slow other processes. - - * Provides option to disable indexing when running on battery. - - * Provides option to index removable devices. - - * Implements the freedesktop specification for metadata - (http://freedesktop.org/wiki/Standards/shared-filemetadata-spec). - - * Extracts embedded File, Image, Document and Audio type - metadata from files. - - * Supports the WC3's RDF Query syntax for querying metadata - - * Provides support for both free text search (like Beagle/Google) - as well as structured searches using RDF Query. - - * Responds in real time to file system changes to keep its - metadata database up to date and in sync. - - * Fully extensible with custom metadata - you can store, - retrieve, register and search via RDF Query all your own custom - metadata. - - * Can extract a file's contents as plain text and index them. - - * Provides text filters for PDF, MS Office, OpenOffice (all - versions), HTML and PS files. - - * Can provide thumbnailing on the fly. - - * It auto-pauses indexing when running low on diskspace. - - - -4 Minimum dependencies - - -4.1 Run-time dependencies (also needed for build) - - * SQLite 3.4 - * libdbus 0.60 - * dbus-glib bindings 0.60 - * GLib 2.14 - * zlib - * intltool 0.3.5 - * GMime - - -4.2 Additional recommended dependencies - - * GStreamer 0.10 + plugins for audio/video file indexing - * xsltproc - * w3m - * wv 1.0.2 - * poppler (pdftotext) - * libvorbis - * libpng - * libexif - * libgsf - * GTK and GNOME stack (for GUI tools) - * libglade 2.5 - * unac (accent stripper) - * exempi - * libxml2 (for extracting html/xml content) - * hal 0.5 (for detection of removable devices, mounted - directories, as well as whether the computer is running on - battery) - - -4.3 For building Tracker's Deskbar-applet backend - - * python-dev 2.3 - * python-gtk2-dev 2.3 - * deskbar-applet 2.16 - - -4.4 Optional run-time dependency - - * xdg-utils (provides some functionality needed by - tracker-search-tool when in a non-GNOME environment) - - - -5 Compilation - - To compile and install Tracker, use the following commands : - - ./configure --prefix=/usr --sysconfdir=/etc - make - sudo make install - - If you install using any other prefix, you might have problems - with files not being installed correctly. (You may need to copy - and amend the dbus service file to the correct directory and/or - might need to update ld_conf if you install into non-standard - directories.) - - -5.1 Notes on Solaris - - To compile Tracker with GCC on Solaris uses the following - commands : - - ./configure --prefix=/usr --sysconfdir=/etc --with-pic \ - CFLAGS=-D_POSIX_PTHREAD_SEMANTICS - make - sudo make install - - To compile Tracker with SUN Studio on Solaris uses the - following commands, because there are some problems to compile - exiv2 using SUN C++ compiler : - - ./configure --prefix=/usr --sysconfdir=/etc --with-pic \ - --disable-warnings \ - --disable-exiv2 CFLAGS=-D_POSIX_PTHREAD_SEMANTICS - make - sudo make install - - -5.2 Compile Options - - Tracker has several compiler options to enable/disable certain - features. The following is a (hopefully complete) listing of - what's available: - - --enable-debug-code : build with debug symbols - - --enable-video-extractor=(gstreamer, xine, external, auto) - - --enable-file-monitoring=(inotify, fam, polling, auto) - - --disable-preferences : disables tracker-preferences capplet - - --enable-deskbar-applet=(auto, handler, module) : enables - Deskbar-applet support; 'auto' should do since it automatically - chooses whether to install the 'handler' (for Deskbar-applet - >=2.16) or the 'module' (for Deskbar-applet >=2.19) - - --with-deskbar-applet-dir=(directory where Deskbar-applet - should find tracker-handler; this should be automatically - detected, perhaps in - /usr/lib/deskbar-applet/{handlers,modules-2.20-compatible}) - - --disable-gui : disables tracker-search-tool build - - --disable-pdf : disables the PDF data extractor - - --disable-exif : disables the exif data extractor - - --disable-libtrackergtk : disables libtracker-gtk build - - --disable-gsf : disables the GSF data extractor - - --disable-warnings : disables GCC warnings - - --disable-unac : disables accent stripping - - --disable-libxml2 : disables HTML/XML extractors (full-text - will still be available) - - --disable-xmp : disables XMP extraction - - --with-session-bus-services-dir=(path to D-Bus services - directory): this should be automatically detected - - --enable-external-qdbm : use system qdbm instead of one included - in Tracker - - --disable-hal : disables HAL support, which is for detecting - whether the computer is running on battery (for EG, determining - whether to run the indexer in such a case), whether a removable - device has been attached (for EG, determining whether to index - its contents), and for detecting mounted directories (for EG, - determining whether to index such) - - --disable-trackerapplet : disables Tracker's notification applet - - - -6 Running Tracker - - -6.1 Usage - - To run Tracker, you need to manually start the Tracker daemon, - trackerd. By default trackerd will index your entire home - directory. - - You can also pass a directory root to be indexed as a command - line parameter if you dont want your entire home directory - indexed. EG "trackerd -i /home/jamie/Documents" (if you want - your home directory indexed when explicily specifying index - directory roots then you must add your home directory to the - arguments: EG trackerd -i /home/jamie -i /mnt/share) - - You can disable indexing by passing "--no-indexing" - - You can enable a low memory usage mode (recommended for - machines with less than 256MB of RAM) by passing - "--enable-low-memory" - - You can artificially throttle indexing by passing - "--throttle=VALUE" where VALUE is in the range 0-20 (with 0, - the default, being fastest and 20 being slowest). Default is - 0. You should only change this value if you want to prevent - noisy fans or hot laptops arising from cpu intensive indexing. - Tracker should have a negligible impact on the system (as it - is scheduled) so you can safely work with it on full throttle - without experiencing slow downs. - - You can specify directory roots to be excluded from being - watched or indexed by passing "--exclude=DIRECTORY" for each - directory root. - - You can specify logging verbosity by passing "--verbosity". Valid - values are from 0 to 3, ranging from least to most verbose - respectively. - - Yet another option is "--language" which allows for specifying - the language to use for stemmer and stop-words list. - - All the above options (and more) can be set by editing Tracker - config file "~/.config/tracker/tracker.cfg" which is created - with specific defaults when non-existent (EG when trackerd is - ran for the first time). Ensure that you restart trackerd for - the changes to take effect. "tracker.cfg" also provides options - that allows Tracker to only index a subset of your home - directory as well as other folders not in your home directory - by setting WatchDirectoryRoots to a semicolon-delimited list of - directories (full path required!) - - EG: - - "WatchDirectoryRoots=directory1;directory2;directory3"" - - An additional option is "--reindex" which indexes user data from - scratch, removing the need to delete Tracker's database manually. - Keywords and metadata definitions are preserved however. - - On the first run, Tracker will automatically create a new - database and start populating it with metadata by browsing - through the user's home directory and/or the root folder(s) - specified. - - On subsequent runs, Tracker will start up much much faster and - will only ever incrementally index files (IE files that have - changed since last index). - - If installed correctly, the Tracker daemon (trackerd) can also - be started automatically via Dbus activation (EG by running - tracker-search SEARCHTERM) - - -6.2 Setting Inotify Watch Limit - - When watching large numbers of folders, its ppossible to exceed - the default number of inotify watches. In order to get real time - updates when this value is exceeded it is necessary to increase - the number of allowed watches. This can be done as follows: - - 1. Add this line to /etc/sysctl.conf: - "fs.inotify.max_user_watches = (number of folders to be - watched; default is 8192)" - - 2. Reboot the system OR (on a Debian-like system) run - "sudo /etc/init.d/procps restart" - - -6.3 Tracker files - - Here is some of the files that Tracker uses during its operation, - apart from "~/.config/tracker" which is stated above, in Sec 6.1: - - * "~/.local/share/tracker" is used for non-expendable content, - like keywords and metadata definitions. - - * "~/.cache/tracker" is used for the expendable indexes and - expendable metadata that can be rebuilt if deleted (this is the - purpose of the ".cache" - its more a permanent tmp directory than - sys tmp but can be deleted if more disk space is needed). - - * The system tmp ("/var/tmp" and "/tmp") is used for short-lived - session data. - - - -7 Tracker & Nautilus Search - - Once you have installed Tracker and have some indexed contents, - you should now compile Nautilus (ver 2.13.4 or higher) which - should auto-detect that Tracker is installed and automatically - compile in Tracker support. You are now ready to appreciate a - powerful and super efficient C-based indexer in all its - glory... happy hunting! - - To make sure trackerd always starts when you login to GNOME, - you will need to add it to gnome-session (select sessions from - preferences menu, select startup program tab and then add - /usr/bin/trackerd). For non-GNOME installations, see the - desktop docs for how to achieve similar. - - - -8 Tracker & Deskbar applet - - Tracker is also integrated in GNOME's deskbar applet. See - Compile Options above on how to get it built. - - - -9 Tracker tools - - Tracker comes with a number of utilities that you can use: - - * "tracker-applet" - notification applet which has various - utilities like displaying Tracker status, indexing progress, - and live statistics, pausing indexing, and launching both - tracker-search-tool and tracker-preferences - - * "tracker-extract FILE" - this extracts embedded metadata from - FILE and prints to stdout - - * "tracker-files" - returns files filtered by the mime type or - their category (see the manpage) - - * "tracker-meta-folder" - return list of files indexed by Tracker - for a folder - - * "tracker-preferences" - GUI tool to set Tracker preferences - - * "tracker-query" - this reads an RDF Query that specifies the - search criteria for various fields. It prints to STDOUT all - matching files. You can see some example queries in the - RDF-Query-examples folder. You can run the examples as - "tracker-query < RDFFILE" - - * "tracker-search SEARCHTERM" - this perfoms a google like search - using SEARCHTERM to retrieve all matching files where - SEARCHTERM appears in any searchable metadata - - * "tracker-search-tool SEARCHTERM" - GUI search utility - - * "tracker-stats" - this displays the current number of indexed - items by category - - * "tracker-status" - queries status of trackerd - - * "tracker-tag" - used for setting and searching tags/keywords - |
