I received a reply from yesterday's post (thank you), but the solution didn't work. When I select a word and do a search, I get a "surface" search … i.e., on the English word selected. I want to do a lemma search on the Greek word behind that English word … but I see no option to do that. This occurs on my Amazon Fire HD Android tablet.
BTW I'm licensed to use Logos 7 Starter on my Windows computer and have whatever flavor of Logos Android on my Amazon Fire HD that goes along with Logos 7 Starter.
