Enhance synonyms feature of the query parser (patch included)

Ranking and term proximity
Hi,
I was reading an article recently about how google ranks results
(among many other things of course) based on the proximity of the
search terms in the source documents. In addition, the position of
the search terms in the search query string itself is also taken into
consideration when determining how important each term is.
Does Xapian do something similar - at least for the first part?
