For Morphological Query searches, it is critical that there be a way to limit the search to a single sentence or clause.
As important as limiting the span to a certain number of words, if the search cannot be limited to a sentence, it will find a lot of false hits. Gramcord could do easily even in 1983, but Logos still cannot do. Accordance also allows searching with sentence or clause boundaries (they call it "scope").
I made this feature request when the Morph Query Builder was being beta tested:

As far as I can see, this has still not been made possible in Logos. I would love to be proven wrong.
Please enable the option in Search Span for number sentences or clauses, in addition to words and verses as there is now. If only one new feature is added, the most critical is the sentence, but clause would be very useful as well.
