just out of interest I looked up ου μη and at least with NA28-T and ESVS in parallel, they don't highlight one another.
Even though 'never/not' is tagged as G3364 ου μη!
Anyway - tagging must be a thankless task - and it works pretty well in 99.9% of cases.
This inconsistency is due to inheriting the Strong's system, which in many cases created distinct entries for common phrases. Accordance is trying to map that Strong's number to a specific lexical form in the GNT, and doesn't find it.
So, we've got two options: program Accordance to lookup one or both of the words (likely just the first), or re-tag this as two Strong's numbers for each word. The latter is the method that I would lean towards since it does not require additional programming support and is actually more accurate in terms of producing search results, etc.
I'll make a note for this to be edited.
Thanks for the feedback.
