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
          interruption.  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
          separated 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
          support, setting this variable in the environment  will  disable
          retrieving  the  locale  from  GConf,  and  the  standard locale
          settings 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
          declaring 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
   information.
