it seems to be related to the spanNear() and/or spanOr() usage that is
injected in the latter case.
this is the query, by the way: "Craniofacial bone screw, non-bioabsorbable,
removing ", sterile" will render results as expected, too. from the bit of
reading i did on the spanquery stuff i was thinking that maybe it was
related to positioning issues, specifically with 'sterile'. in the Analysis
tab, however, it's in position 6 in both indexing and querying output.
