I have read all of the wikis and posts that I could find on syntax searches in L4 and watched all of the videos. With all of the trial and error, I am making progress on using this tool, but I am not having much success with a particular search. It seems like it ought to be fairly simple. I ran the search in L3 a few years ago and thought I would see what L4 came up with. The structure is Galatians 5:5 - a verbal form (middle/passive, if possible) modified by a dative noun and πίστις in the genitive. L3 returned three results (Gal 5:5, Eph 2:8, 1 Pet 1:5). Most of my searches in L4 returned Gal 5:5 (along with multiple other verses), only one returned Eph 2:8, and none returned 1 Pet 1:5. Here is the closest I got:

Can anyone help me expand this search to include all instances of a verb that is modified by a dative and πίστις in the genitive? I've already spent way too much time on it.
Is it possible to do this kind of search in the LXX?
Also, several search attempts, like this one, resulted in L4 crashing:

Is it just too much to handle?
