I wanted to do some supportive reading on biblical theology. I have received several books on biblical theology, (some I purchased individually and some as part of a set). I'd like to create a rule that pulls them together. However, whenever I try to gather than by title, I know some are missing. When I try to include them as a series, I get unrelated books to the topic. I tried using the Wiki page, but I'm not really seeing what I need to do. Does anyone have a suggested rule for collecting together books on biblical theology from one's library?
Here's the current rule I tried using (the one that has gotten closest to my desired result):
(title:(Biblical, “Old Testament”, “New Testament”) AND title:theology) OR (subject:(“bible. o.t.—theology”, “bible. n.t.—theology”, “bible.—o.t.—theology”, “bible.—n.t.—theology”))
