This shouldn't be one's introduction to Morphological Searching. What on earth is Andersen-Forbes Aram..?

This is not much better ...

Suggest that something more intuitive than obscure types of morphology confront the (average) user:-

===============
Poor man's Genitive Absolute (using above NA27):
@V??P??G BEFORE 3 words @NG produces 342 in 162 verses
The Morph dialog box hindered trying to type @JG as an OR'd term:-
@V??P??G BEFORE 3 words (@NG, @JG)
But the result was ZERO.
BUG: This is a legal query in v3 Morph Search (and see last query)
(@V??P??G BEFORE 3 words @NG) OR (@V??P??G BEFORE 3 words @JG) succeeded with 426 in 187 verses.
I tried a query with OR'd text terms:-
@V??P??G BEFORE 3 words (false, many) produced 23 in 9 verses.
BUG: the various results include glosses like much, more irrespective of "Match all word forms".
