In the snapshot below I have the match within menu open and it looks like there are only two options to constrain your search down to - Verse and Chapter.
In Accordance I am able to constrain the search to within a paragraph, clause or sentence. This can come in pretty handy when you are trying to find a passage that you know a few key words for but those words span over the sentence or clause. And that sentence or clause may be several verses.
Is there another way in Logos that a sentence or clause search can be accomplished?
