jarri, I'm sorry that the Mambot is not working for you. There must be some setting in your SMF installation that we are missing. The only reason I think that it might be your SMF installation, is because this seems to be an isolated incident. Another user, aravot, is using a similar configuration as you but the Mambot is working fine. The only way I would know for sure wat was going on is by looking at your smf_boards database table. Since this isn't likely, I'm afraid I can't offer a solution at this time.

I really can't fix a problem if I can't duplicate it.
As for the dispay order of the search results, that is an issue with Joomla. Joomla access the Mambots in the order you have them arranged in the Admin Control Panel. It then returns all of the results for that Mambot then moves to the next mambot. If you have 3 or more Mambots all returning results for a query, you'll notice that they are grouped by each Mambot that returned them.
Thank you for your cooperation and patience with the developement of this Mambot. I'm sorry that you couldn't have benefitted more from it.
