Well, I can't reproduce the problem at my end. Actually, I inadvertently did when I first tried to, but that was because I had two definitions of prefix_match_character in my test config file. If you just have the one definition of prefix_match_character, and it's set to "*" (which is the default if you have no prefix_match_character definition in your config), then it should work fine. See also http://www.htdig.org/FAQ.html#q5.31 Note that there's no "speling" fuzzy algorithm in 3.1.6, though, it's only in 3.2 betas. The one difference I encountered between 3.1.5 and 3.1.6, as far as the handling of prefix_match_character is concerned, is that if you set prefix_match_character to an empty string, then the "*" is stripped out of a word in 3.1.5 but not in 3.1.6. So, if prefix_match_character is empty, htsearch 3.1.5 would still handle a search for "esenci*" as though prefix_match_character were set to "*" - in reality as though you had typed "esenci". Not so for 3.1.6, though, because the "*" isn't stripped out (because it's the default wildcard for the "match all documents" facility when prefix_match_character is empty). -- Gilles R.
