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 and 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.

       -m, --low-memory
              This changes the behavior of the database manager and some other parts of  tracker-
              store  to  be  optimized  for  lower memory systems by lowering database connection
              cache sizes and page sizes for example. This may slow down indexing performance.

       -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.
