One of my most favorite features in Logos is doing word studies in contemporaneous literature of the NT. In order to serve that purpose I have created several collections, for example:
- Greek: Contemporary NT: 200BC - 100AD (Greek)
- Greek: Contemporary NT: 200BC - 100AD (English)
Both collections are identical in terms of authors and title, the only difference being the language. See screenshot of the collections attached.

If I search in the Greek collection for EITHER lemma:κοινός OR lemma:σωτηρία (I mean two separate searches), ONLY THEN can I find the English counter-collection when I click 'Add Versions'.
However, if I combine the two searches with the following query:
- lemma:κοινός WITHIN 3 WORDS lemma:σωτηρία
then the English collection has disappeared from the Add Versions list! See screenshot.
Strangely enough, if I search for the same combined query in another Greek Collection (which I called "All Greek Literature Before the NT"), then the Add Versions feature DOES allow me to choose the English counter-collection.
Any support would be hugely appreciated!
