I've played with this a bit now as I recently got the syntax module for the GNT-T and have been wanting to try it out a bit. Had to read a bunch of stuff and still do not really know what I'm doing. But below are three queries. One very broad that will find Matt 7:28 based on your initial post. Then one that I thought should have worked based on the syntax diagram but it did not. Then finally after many variations one that does find Matt 7:28 and similar constructions.
If anyone can explain what I did I'd be really interested to understand it. To me the search I constructed does not appear to reflect the syntax diagram so I am not sure how these the search and diagram relate to one another. And along the way I found many as yet curious results. I am yet to go through Marco's posts on various syntax searches but there does not appear to be one aimed at precisely this sort of search, at least at a quick glance.
For comparison purposes I got 15 hits in 8 verses - Matt, Mark and Jn and the Jn could be excluded by including only dative articles I would think. BTW I also don't fully understand the hit count here. Need to look at that a bit.
Anyhow enjoy - time for me to do vocab drills.
