Is it possible to do an advanced search using mime type? What's the syntax if so?

Also, is there a reference document with all the available search terms? I've tried the help files and Google searches and searches on the Laserfiche support and Answers sites but haven't been able to find a comprehensive resource for it. (Apologies in advance if it's somewhere obvious that I've overlooked).

I'm using LF 10.1 but will soon be on LF 10.2.
