Comment(by tack):

 The (Python) code that generates the query from step 4 looks like:

 {{{
 filtered = [re.sub(r"[^\w_']+", '', word) for word in phrase]
 qs = [xapian.Query(word, 1, pos+1) for pos, word in enumerate(filtered) if
 word]
 query = xapian.Query(xapian.Query.OP_PHRASE, qs)

 enquire = xapian.Enquire(xapdb)
 enquire.set_query(query)
 enquire.set_collapse_key(1)
 enquire.set_sort_by_relevance()
 matches = enquire.get_mset(0, 5)
 }}}

 If I comment out enquire.set_collapse_key(1), the problem goes away.

 Value 1 exists in each document added to the database and is an integer
 serialized with xapian.sortable_serialise().
