Actually the apt backend can make use of xapian and so would already
support an advanced syntax.

We should support the basic operations most people use when searching in
google: multiple key words. But I don't see a reason not to silently
support regular expressions or boolean operations.

I even have got a bug report about not working multiple keywords.
Furthermore personally I regularly search for more than one term and
expect from every search machine (in the web or in programs) to support
this naturally.

Why add this to the client side? Clients should be as tiny as possible.
If you don't want to have this in the backends you should add this to
the packagekit daemon. But this could be a slow down: running the search
over the cache several times and merging the results.
