What are the main advantages installing XenForo Enhanced Search? My board is not so big (about 260.000 posts) but I'm searching for something that gave me better results when someone search for something in my board.
I've read that it requires elasticsearch that I really don't know. It's something I've to ask to my service provider to install on my server? It's free? Does it impact my server's performance? I've a dedicated server where my board run with many other domains so I've full access to my server.
Thanks for your suggestions...
