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

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