Improved matching capability of Rares-style fuzzy-join rule that is more consistent with the index based matching. Added indexed-NL-join hint to resolve choice between Rares-style fuzzy joins (where applicable) and index based fuzzy joins. Enabled a few Rares-style fuzzyjoin tests that used to break.
