It is not very advanced to capture nuances (direct SQL matching only) but it still provides the forum a very useful tool. I would say it is more useful than the standard XF search as it responds immediately and doesn't have to redirect you to a new page. Thank you.
The author completely ignores request or messages posted in his releases, so if you have custom requests or problems, unless you directly reach him out, get ready to be ignored. Besides that, the add-on works fine with the standard provided features.
I didn't know where to leave my rating as I use a few of your add-ons. Andy is a great guy and very helpful. If you have any issues, he will try and resolve it for you. Also the $25.00 for all add-ons he releases is a bargain. Best $25.00 spent!
