First, I put together a simple search for verbs in the Hifil Binyan that are governing two complements. When I simply ask for two complements within the predicate phrase it works fine:
[Predicate] [Complement Phrase] [Complement Phrase]
Next I wanted to exclude all the complements marked by prepositions, so in each complement phrase I specified that the first item should be a noun, definite article, or object marker:
[Particle (Object, Article)]
[Place = 1]
After I run it like this, I am also getting hits where the verb governs a single complement but that complement is itself composed of a compound phrase, for instance
Gen 3:16 הַרְבָּ֤ה אַרְבֶּה֙ עִצְּבוֹנֵ֣ךְ וְהֵֽרֹנֵ֔ךְ
'I will in fact increase your pain and your conception'
(which BTW is a proper example of hendiadys, I forget who brought that up on a different post)
I cannot figure out any way to exclude these. The problem seems to be that the NPs inside the coordinated phrase are treated as being at depth 0 themselves.
Second, when there are three items (A, B, C) in a construct, does search both directions literally mean both directions so that you only hit on A + B + C or C + B + A? Or does it look for every possible combination, like B + C + A or A + C + B?
