tracker-search
tracker-search(1) User Commands tracker-search(1) 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-all Display all help options available. -l, --limit=N Limit search to N results. The default is 10 or 512 with --disable-snippets. -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 --disable-snippets Results are shown with snippets. Snippets are context around the word that was searched for in the first place. This gives some idea of if the resource found is the right one. Snippets require Full Text Search to be compile time enabled AND to not be disabled with --disable-fts. Using --disable-snippets only shows the resources which matched, no context is provided about where the match occurred. --disable-fts If Full Text Search (FTS) is available, this option allows it to be disabled for one off searches. This returns results slightly using particular properties to match the search terms (like nie:title) instead of looking for the search terms amongst ALL proper- ties. It is more limiting to do this, but sometimes searching without FTS can yield better results if the FTS ranking is off. --disable-color This disables any ANSI color use on the command line. By default this is enabled to make it easier to see results. --music-albums and --music-artists. -f, --files Search for files of any type matching EXPRESSION (optional). -s, --folders Search for folders matching EXPRESSION (optional). -m, --music Search for music files matching EXPRESSION (optional). --music-albums Search for music albums matching EXPRESSION (optional). --music-artists Search for music artists matching EXPRESSION (optional). -i, --images Search for images matching EXPRESSION (optional). -v, --videos Search for videos matching EXPRESSION (optional). -t, --documents Search for documents matching EXPRESSION (optional). -e, --emails Search for emails matching EXPRESSION (optional). Returns a list of subjects for emails found. -c, --contacts Search for contacts matching EXPRESSION (optional). Returns a list of names and email addresses found. --software Search for software installed matching EXPRESSION (optional). Returns a list of desktop files and application titles found. --software-categories Search for software categories matching EXPRESSION (optional). Returns a list of urns and their categories (e.g. Settings, Video, Utility, etc). --feeds Search through RSS feed information matching EXPRESSION (optional). Returns a list of those found. -b, --bookmarks Search through bookmarks matching EXPRESSION (optional). Returns a list titles and links for each bookmark found. -V, --version Print version. SEE ALSO
