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
       itself, 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=debug.

       -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
              interruption 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_PRAGMAS_FILE
              Tracker  has  a  fixed  set  of PRAGMA settings for creating its
              SQLite connection.  With this environment variable pointing to a
              text file you can override these settings. The file is a \n sep-
              arated list of SQLite queries to execute on  any  newly  created
              SQLite connection in tracker-store.


       TRACKER_DISABLE_MEEGOTOUCH_LOCALE
              If  Tracker  is  compiled with meegotouch locale management sup-
              port, setting this variable  in  the  environment  will  disable
              retrieving  the  locale from GConf, and the standard locale set-
              tings will be used instead.


       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.
