I have been using the 28th edition of the Nestle-Aland Greek NT.Grammatical Constructions correctly identifies the existence of a construction (e.g., εἴ γε in Ephesians 3:1, but when I choose "Search this Resource" (either as a new search pane or as an inline search), the result is always "0". If I change versions to NA27, it seems to work.
I get the same error in:
The Lexham Syntactic Greek New Testament
The Lexham Syntactic Greek New Testament SIL edition
The Lexham Greek-English Interlinear New Testament
The UBS4 Interlinear
The UBS4
But no error in:
The Lexham Discourse Greek New Testament
NA27
SBL edition of the Greek New Testament
The ESV
I haven't tested this on any other versions.
Anyone else have this problem, or is it a problem?
