Although Charles is right about the length of the word βnewβ, there is another problem here β even reindexing with a shorter minimum word length (not quite practical), you will get content containing the words βnewβ and βnewβ, york and a lot of words between them, but not necessarily just the string "New York".
In addition, there is a good chance that the word βnewβ is in more than 50% of your records, so records for it are not returned.
I came up with a way to enable exact matching of strings with full-text indexes a couple of years ago - although I never got around to including logical search mode as well.
