I don't understand what you mean by the search is blury or what's awful about the pagination. More feedback is certainly welcome, but please understand we're simply using Kunena here so we'll do what we can within the limitations of Kunena. Any general feedback you have for Kunena should be reported to Kunena as well so they can further improve it. We report as much feedback as we can as well.
For Google searching if you use the following you can narrow results down to our forums, but Google can be slow indexing new posts. We'd much rather improve our onsite searching as much as possible.
