[Tracker] PATCH: regular expression searching

[Samuel <sciyoshi gmail com>]

Hey again,

I was wondering if you would be interested in including this patch
into Tracker. It implements regular expression searching using MySQL's
REGEXP, and works pretty well. Note that the patch is against 0.0.4,
not CVS. I noticed you added startsWith support, and regex is a
natural extension. With this included, you can do an RDF search such
as:

<rdfq:rdfquery>
 <rdfq:From eachResource="Files">
   <rdfq:Select>
     <rdfq:Condition>
       <rdfq:regex>
         <rdfq:Property name="Audio.Title" />
         <rdf:String>Lazy|Kid</rdf:String>
       </rdfq:regex>
    </rdfq:Condition>
  </rdfq:Select>
 </rdfq:From>
</rdfq:rdfquery>

which allows for more fine-grained control on searches.

On another note, I'm also thinking about writing a tutorial on the
Python D-Bus bindings, and once the Tracker D-Bus API stabilizes a
bit, how to search using Tracker from Python. When you get the website
up, I'd be glad to send it to you :-)

Cheers,
Samuel
