Can the Unity dash search for content within files?

Will Unity Search have support for content search? I know tracker can index your files and you can then search for them, but is it possible to get this with "in" unity?

use case:

1. I click the super key and search for "lamda" and I get the pdf and py files where this string is located (Maybe with a preview of the files?). Also if the file with name lamda.odf will be shown

Install recoll-lens (as of 26 March 2012 this works only for 11.10):

sudo add-apt-repository ppa:recoll-backports/recoll-1.15-on
sudo apt-get update
sudo apt-get install recoll-lens recoll

Run recoll (open dash, type recoll and there you are), and create an index (it might take some time) - the app will ask for it itself when first run. (In preferences, you may want to set it up so that it reindexes your files regularly or on the fly.) Then logout and login and you have a new lens that provides full-text search. It is accessible from general Dash as well (after hitting super).

We are using zeitgeist to get the search done in Unity. Zeitgeist is using a "fts" extension (full text search) which is enabled by default in ubuntu.

So, if you opened your file already, you will be able to find it typing some keywords from its content in the file lens.
