[Tracker] Common words not indexed

["Haim Roitgrund" <haim roitgrund gmail com>]

Hello.

I've been using Tracker for a while now.
I'm very pleased with it, and appreciative of the development it's clearly benefited from since I last tried.

Can you please help with an issue of indexing?
When I search for some specific words, such as 'India' or 'points', I have no trouble.
When I search for any of the following, however, I get no results: 'and', 'even', 'still' or 'only'.

Clearly, common link words are not being indexed.

How can I get around this? Is this due to the 'unique words' ceiling? I've left it on its default of 10,000.
I'd gladly go higher if this can help.

Thank you kindly,
jackn
