Perhaps you should try some spelling variations:
associated factors » associated bacteria
associate director » associated vector
associate editors » associated pastors, associated vectors, associated operators
associate editor » associated vector, associated factor, associated motor
associate factor » associated vector, associated fatty

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: ((((associate editor) OR (associate editors))) OR (((((associate factor) OR (associated factors))) OR (associate director)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((associate editor) or (associate editors))) or (((((associate factor) OR (associated factors))) or (associate director))))".
• Adding a wildcard symbol may retrieve word variants: ((((associate editor) or (associate editors))) or (((((associate factor) OR (associated factors))) or (associate director))))*.
