How to Perform a Search Within Events?

Hi,

Basically I want to use Python and be able to search my calendar for
events containing a certain word like "dentist" in the title or
description.  I haven't found an API that does this, but I already have
most of the http machinery built and really just need to figure out the
concept.

I'm thinking A.) Do I download the whole calendar via my private feed
and then parse the XML and search that, or B.) is there a way to send a
keyword type query to the API to have it do the search for me?

And finally B.) part 2, if I plan on making lots of search calls, would
it still be better to save the full calendar and then search the xml?

I tried to research this myself but the date range query seems to be in
Java and not XML.

Thanks,

Greg
