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

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 (associated pastors))))) OR (associated vector)).
• Adding a wildcard symbol may retrieve word variants: ((((associate editor) or (((associate editors) or (associated pastors))))) or (associated vector))*.
