This is what an ideal search system should be. You can't go back after experiencing instant search results and autocomplete. Similar threads functions is a bonus. It is a well thought, well coded addon.
Xon is professional and helpful.
The support Xon has showed thus far has been fantastic! The bug fixes are rather swift and has implemented a feature that was suggested to be added. His work is very professional and clean, I would highly recommend this add-on!
That is one of Xon's awesome add-ons. It brings new features like "similar threads" and one of the best features is the "search bar auto complete"-function which really brings up the results you need when you search for something. Many options to configure and well-thought-out.
Great developer and very responsive for suggestions.
I have been working with @xon on getting the XF2 version to match the XF1 version when it comes to relevant threads, I can only say he has been extremely professional, receptive and prompt in providing me versions to test on my test forum. Also this addon is worth its weight in gold :)
