I like that they have an option for multiple languages, so I can customize my results. It's not very intuitive at first, but once you get used to it, it's pretty easy to use. The language selection menu is a bit confusing (although I'm sure it could be improved). I don't know if this was intentional or not, but when I search for something in English it sometimes returns results in Japanese. It's probably just me though (I do know how to fix it). But other than that, I've had no issues. We are using Searchman for some of our internal tools. It really helps with the overall search flow of our website as well as improving our overall mobile presence.
