Perhaps you should try some spelling variations:
associated factor » associated factors, associated pastors, associated vectors
associated vector » associated factors, associate director, associated secretory
associate editor » associate editors, associate director, associated motor
associate factor » associated factors, associate director, 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 (associated vector)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((associate editor) OR (associated factor))) or (associate factor))) or (associated vector))".
• Adding a wildcard symbol may retrieve word variants: ((((((associate editor) OR (associated factor))) or (associate factor))) or (associated vector))*.
