Perhaps you should try some spelling variations:
overlapping magisteria » nonoverlapping magisteria
overlapping registers » overlapping clusters, overlapping regions, overlapping regulatory
overlapping matrix » overlapping metrics, overlapping matches, overlapping data

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: non-((((overlapping magisteria) OR (overlapping registers))) OR (overlapping matrix)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "non-((((overlapping magisteria) OR (overlapping registers))) or (overlapping matrix))".
• Adding a wildcard symbol may retrieve word variants: non-((((overlapping magisteria) OR (overlapping registers))) or (overlapping matrix))*.
