Because you are collapsing multiple matching documents into 1 hit,
xapian has to find more documents to get the same number of hits.

If you are using omega you could try reducing MIN_HITS (may be called
MINHITS now) which reduces how many results xapian tries to find, but of
course also reduces the accuracy of how many hits xapian thinks there
might be.
