I was running this search hoping to locate all the places where ἐν τῷ is followed by a present (either middle or passive) infinitive.
"ἐν τῷ" BEFORE 1 WORD morph.g:VP[MP]N
It returns 12 results in 6 verses in the NA28. But it doesn't return four verses (Luke 9:29,33; 10:35; 17:11) where the present infinitive is tagged "either middle or passive".
What is the point of this designation? It has the effect of hiding results.
