I searched for "God's Word Translation" in my Logos library on my Android phone, and it did not find it, even though I do own it.
Turns out the problem is that the title of the book has a smart apostrophe in it, and my search text had a regular apostrophe (you can't even type in a smart one in the search box). Either kind should be matched.
This same problem exists on the web app. See cross-posting here: https://community.logos.com/forums/t/147739.aspx
