Searches are indefinitely long on my tablet and I pretty much always give up whenever I try one. For instance, last Sunday in church. I ran a basic search on "bar mitzvah" all library, but had to give up, after waiting for 5 minutes. Then searched for "my father" in one Bible, ESV (I tried LEB later), same deal.
I run an Intel based tablet, the Dell Venue 8, and I am wondering if it is part of the problem? I would be interested in hearing about others' experience with searches offline in the Android app.
