Maybe I'm blind, but I don't see a Logos.com tag for this 'discussion'.
After the great news, the Hebrew Encyclopedia was 'almost' ready, I had to make sure another Accordance resource (Talmud Biblical Indexing) wasn't possibly available in some form on Logos.com
So, I searched 'Talmud index' (not in quotes) on Logos.com.  I got only 3 resources back, none having Talmud or index in the title. Two were indirectly Talmud but the 3rd who knows. 
Apparently you have to literally tell it 'or' or maybe a comma … not 'and' or who knows.   It doesn't know to first look for 'and' (the typed syntax) before looking for a possible 'or'. 
I just don't get it what they're doing.  Anyway I got my Accordance volume and I'm happy (as I am with the coming Logos  Hebrew resource!).
And … BTW … going back to Accordance, I typed in a quick phrase … found the book, quick.
