[Bug 1666676] Re: Install tracker by default

[Khurshid Alam]

@Carlos Garnacho

I have tested this on a low-end laptops first with no tracker and then
with tracker installed with default configuration (and there our problem
lies.) The default configuration is just unacceptable.

1. Why does tracker index bzr, vendor, pycache folders by default? I put
my git projects inside documents. You can literally see that with
tracker daemon -f. Also, It should ignore any directory starting with
"." by default

2. There are many other configuration available in Gsettings which
aren't exposed in GUI.

3. I configure following things:
    -- enable-writeback false 
    -- index-optical-discs false
    -- index-on-battery false
    -- index-removable-devices false 
    -- ignored-directories ['core-dumps', 'CVS', 'lost+found', 'po', 'vendor', '.git']
    -- ignore-stop-words true
    -- ignore-numbers true
    -- max-words-to-index 1000
    -- removable-days-threshold 3 ? (I don't not understand this)

After this the system is somewhat working well. There are no aggressive
indexing. All files can still be searched from shell. Documents, Bijiben
etc works without any problems.

There are many options which can be disabled during compilation. For
example extractor metadata for ps.gz, gif, iso, xps, abw seems pretty
useless to me (who use it and why?). These can be disabled during
compilation.

I will keep testing but I believe tracker can be enabled in Ubuntu with
proper default settings keeping it at absolute minimal level.

Title:
  Install tracker by default

Bug description:
  For Nautilus' built-in search to not be very slow, Nautilus needs to
  use tracker for search.

  This is especially important since it's being seriously proposed for
  Ubuntu 17.10 that we drop the "type-ahead search" patch that reverted
  the removal of that feature by Nautilus years ago. (LP: #1666681)

  To not cripple Ubuntu GNOME, it was previously decided to let Nautilus
  build against tracker but not use that functionality on Unity. See
  this patch:

  https://bazaar.launchpad.net/~ubuntu-
  desktop/nautilus/ubuntu/view/head:/debian/patches/ubuntu_tracker_only_on_GNOME.patch

  This bug is requesting that patch be dropped and the extra tracker
  components be allowed into main and installed by default in Unity.
