Perhaps you should try some spelling variations:
associate director » associated vector
associate editor » associate editors, associated vector, associated factor
associate factor » associated factors, associated vector, associate editors
associated fatty » associated fauna, associated factors, associated states

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