tracker3-search - Search for content by type or across all
  types
tracker3 search [options...] [[expression1]
    ...]
tracker3 search searches all indexed content for
    expression. The resource in which expression matches must
    exist (see --all for more information). 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.

  logical AND. For logical OR operations, see -r.

-v, --videos

-c, --contacts

  (optional). Returns a list of desktop files and application titles
  found.
--software-categories

  (optional). Returns a list of urns and their categories (e.g. Settings, Video,
  Utility, etc).
--feeds

  expression (optional). Returns a list of those found.
-b, --bookmarks

  (optional). Returns a list titles and links for each bookmark found.
-l, --limit=<limit>
Limit search to limit results. The default is 10
  or 512 with --disable-snippets.
-o, --offset=<offset>
Offset the search results by offset. 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
  properties. 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.
