Comment (by olly):

 JFD mentioned the cases of `OP_PHRASE` and `OP_NEAR` used in subqueries,
 which have an obvious meaning (approximately they occur where they match
 at the location of each term for that match).  Currently the positional
 check exits as soon as it finds a match in a given document - when used in
 a subquery it would need to (potentially) keep going and find all matches.
