How can I search for any form of the greek noun "pistis" followed by any noun or pronoun in the genitive case?
You need to do a morph search in a Greek New Testament. Different NTs have different morphologies, and therefore different syntaxes. This one will work for NA27:
(lemma:πίστις BEFORE 1 WORD @NG) OR (lemma:πίστις BEFORE 1 WORD @R??G)
You don't need to remember that @R??G is a genitive pronoun. Just type the @ sign and click on the dropdown menu.
You can also perform a Bible search using the following criteria. It gives the same results, but it's harder to construct:<lemma = lbs/el/πίστις> BEFORE 1 WORDS (<lbs-morph+el ~ NG???>, <lbs-morph+el ~ R??G???>)
