NAME

       tracker-search - Search all content for keywords

SYNOPSIS

       tracker-search [OPTION...] EXPRESSION [EXPRESSION...]

DESCRIPTION

       tracker-search  searches all indexed content for EXPRESSION. The resource in which EXPRESSION matches must exist (see --all for more infor-
       mation). All results are returned in ascending order. In all cases, if no EXPRESSION is given for an argument (like --folders for  example)
       then ALL items in that category are returned instead.

       EXPRESSION
	      One or more terms to search. The default operation is a logical AND.  For logical OR operations, see -r.

OPTIONS

       -?, --help
	      Give a short help message.

       -l, --limit=N
	      Limit search to N results. The default is 512.

       -o, --offset=N
	      Offset the search results by N. For example, start at item number 10 in the results. The default is 0.

       -r, --or-operator
	      Use OR for search terms instead of AND (the default)

       -d, --detailed
	      Show the unique URN associated with each search result. This does not apply to --music-albums and --music-artists.

       -a, --all
	      Show  results  which might not be available. This might bebecause a removable media is not mounted for example. Without this option,
	      resources are only shown if they exist. This option applies to all command line switches except --music-albums and --music-artists.

       -f, --files=EXPRESSION
	      Search for files of any type matching EXPRESSION (optional).

       -e, --folders=EXPRESSION
	      Search for folders matching EXPRESSION (optional).

       -m, --music=EXPRESSION
	      Search for music files matching EXPRESSION (optional).

       --music-albums=ALBUM
	      Search for music albums matching ALBUM (optional).

       --music-artists=ARTIST
	      Search for music artists matching ARTIST (optional).

       -l, --images=EXPRESSION
	      Search for images matching EXPRESSION (optional).

       -v, --videos=EXPRESSION
	      Search for videos matching EXPRESSION (optional).

       -t, --documents=EXPRESSION
	      Search for documents matching EXPRESSION (optional).

       -e, --emails=EXPRESSION
	      Search for emails matching EXPRESSION (optional). Returns a list of subjects for emails found.

       -c, --contacts=EXPRESSION
	      Search for contacts matching EXPRESSION (optional). Returns a list of names and email addresses found.

       -V, --version
	      Print version.
