each file manager is going to have some pros and cons...
I've run into some problems with many Explorer replacements, but I need to deal with multiple languages, which many can't handle properly for what I need.
But overall, the ones I've tried/buyed, are all pretty good. It's a mature market, so it's hard to find one of the mature ones that doesn't do what you want.
For search, just try them and see what you like.
