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_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.
