I'm learning to build syntax searches, and I'm trying to use syntax search to see if I can get the same results as using the Grammatical Relationships function. I tried to look for instances of υἱός used adjectivally with θεός using the following syntax search:

This search, however, returned only 38 results, which is fewer than the results I get from Grammatical Relationships. It's missing Mt 26:63; Mk 5:7; etc. How should I modify my syntax search?
Strangely, John 1:34, for example, appears in my syntax search but NOT in Grammatical Relationships. Is there a grammatical reason why this verse is excluded?
