Manually one could search for:
[VERB]@εισ* <FOLLOWED BY> <WITHIN 2 Words> [prep]@εις
and get 23 examples in Mark (46 "hits" since it counts both words), all of which are valid instances of what I'm looking for. Then one could do the same with ἐκ (9), ἀπο (5), etc. With ἐκ you also have to allow for ἐξ-, etc.
I realize this is a bad week to be asking technical questions since the Accordance team is mostly in Boston, but perhaps they will check in occasionally or someone else has solved this perplexity already.
