I agree that more thorough tes coverage would be good, but frankly, I'm at loss what could be reliably tested.

"Works faster with fuzzy lookup" would be the gist of functionality, but that can't be reliably tested without enormous data set.

Other option would be inserting a record in indexed table, opening dba connection and checking that multiple tokens have been inserted in the INDEX$I table according to prefix length rules. However, wouldn't that be too much digging around DB internal implementation of the feature?
