Perhaps you should try some spelling variations:
observational clinical » observation clinical, observations clinical, observational logic
observational concepts » observation concepts, observational concerns, observational conceptual
observation conceptual » observational conceptual, conservation conceptual, observation concept
observational cinema » observational context, observational economy, observational clues

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: ((((observational cinema) OR (observational clinical))) OR (((observational concepts) OR (observation conceptual))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((observational cinema) OR (observational clinical))) or (((observational concepts) or (observation conceptual))))*".
