However, after trying a few others, I gave it a shot and it works great out of the box. Don't have a single bad thing to say about it, even had more features than I originally thought it did.
The complaints I see here in the reviews don't make a lot of sense to me personally, maybe they're having problems with other plugins they have creating conflicts?
Anyways, you can see where on one site I made at boisebarguide.com I deleted the default search module, installed rokajaxsearch and set it to the search position using their dark theme style. It was literally that quick, took about 30 seconds and I had nice ajax driven search that matches the template. I wish every other module worked this well.
They also have great customer feedback for their supported systems. However, don't try to contact them for a custom installation on a cms they don't support. I wanted to use it on pligg, and so sent a ticket to them asking how it could be done and was completely ignored. I won't take a star off for that though because this rating is for Joomla. Honestly you can't beat it.
Thank you for your review.
KeyCAPTCHA for pligg is in our queue now. We are going to publish it in 3-4 months.
However, as far as the plugin itself goes. Works great, easy to customize with the css. It turns your meta keywords for articles into tags which is nice to have without having to go to k2. I haven't seen a single bad thing to say about the plugin.
Unlike some of his other extensions this doesn't have a mandatory link back to his site, so it's truely free.
Like all his extensions I've tried, it's also very well coded and usually has no issues regardless of any other extensions you might be using.
