NAME
       tracker-store - database	indexer	and query daemon

SYNOPSIS
       tracker-store [OPTION...]

DESCRIPTION
       tracker-store  provides	both  a	 powerful database daemon which	allows
       clients to query	or update their	 data  using  the  highly  descriptive
       SPARQL language.

       tracker-store  does  not	do any file crawling or	any mining of data it-
       self, instead other processes do	that while tracker-store serves	 as  a
       daemon  waiting for such	requests from application miners like tracker-
       miner-fs.

OPTIONS
       -?, --help
	      A	brief help message including some examples.

       -V, --version
	      Returns the version of this binary.

       -v, --verbosity={0|1|2|3}
	      Sets the logging level, 0=errors,	1=minimal,  2=detailed,	 3=de-
	      bug.

       -r, --force-reindex
	      This  forces  tracker-store  to remove databases and to recreate
	      fresh databases ready for	data insertion from  the  miners.  For
	      more information about the miners, see tracker-miner-fs.

       -n, --readonly-mode
	      This  starts  tracker-store  in a	mode which disables writing to
	      the database. Only SPARQL	read requests can be serviced if  this
	      option is	used.

ENVIRONMENT
       TRACKER_DB_ONTOLOGIES_DIR
	      This  is	the directory which tracker uses to load the .ontology
	      files from. If unset it will default to the correct place.  This
	      is used mainly for testing purposes.

       TRACKER_LANGUAGE_STOP_WORDS_DIR
	      This  is the directory which tracker uses	to load	the stop words
	      dictionaries from. If unset  it  will  default  to  the  correct
	      place. This is used mainly for testing purposes.

       TRACKER_STORE_MAX_TASK_TIME
	      This  is maximum time allowed for	a process to finish before in-
	      terruption happens. The actual moment  of	 interruption  depends
	      also on the frequency of checks. The value 0 indicates no	inter-
	      ruption.	This environment variable is used mainly  for  testing
	      purposes.

       TRACKER_STORE_SELECT_CACHE_SIZE / TRACKER_STORE_UPDATE_CACHE_SIZE
	      Tracker  caches  database	 statements  which occur frequently to
	      make subsequent repeat queries much faster. The  cache  size  is
	      set to 100 by default for	each type (select and update queries).
	      This must	be at least 2 as a minimum, any	less and a value of  3
	      is  used	instead.  The  number  represents the number of	cached
	      statements to keep around.  This environment  variable  is  used
	      mainly for testing purposes.

       TRACKER_USE_LOG_FILES
	      Don't  just log to stdout	and stderr, but	to log files too which
	      are kept in $HOME/.local/share/tracker/. This came  into	effect
	      in  0.15.3 and 0.16.0. After this	version	of Tracker, logging to
	      file (usually useful for debugging) can only be done by  declar-
	      ing this environment variable.

       TRACKER_USE_CONFIG_FILES
	      Don't  use  GSettings,  instead use a config file	similar	to how
	      settings were saved in 0.10.x. That is, a	 file  which  is  much
	      like an .ini file.  These	are saved to $HOME/.config/tracker/

NOTES
       tracker-store is	highly bound to	the D-Bus freedesktop project. A D-Bus
       session is needed for all Tracker processes to communicate between each
       other.	D-Bus  is our acting IPC. See dbus-daemon(1) for more informa-
       tion.
