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

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