Brilliant solution! In fact, there was a time when we mistakenly disabled the addon and our users were "forced" to use "enhanced search) and quickly stated (complained?) that they wanted the ThreadLoom search back.
We've been using Threadloom Search for years. Our users love it, and we've had nothing but good vibes and interactions with Threadloom. I don't have hard data to back it up, but I'm confident our users are finding much more relevant information, and finding it easily :)
We've been with Threadloom since their beginnings back in 2016 and the team has been a pleasure to work with. It is refreshing to see a company focussed on making the forum experience relevant in the social media era. Threadloom search returns better results than the native or Elastic search, and everything is handled in the cloud taking a huge search strain off our servers. Highly recommend giving it a try!
