On way of doing this is to place the release date in a value, and
configure the QueryParser to use the value range syntax. See
<http://xapian.org/docs/valueranges.html> for more detail. I believe
all the functionality should work fine from PHP5.

For languages, if you stash the language of a document in the document
data, you can grab that out of each match to find out the languages in
a (part of) the match set, although that's a bit messy. There may be a
better solution to this.
