Perhaps you should try some spelling variations:
associated factor » associated factors, associate factor, associated pastors
associated vector » associated factors, associate director, associated secretory
associate editors » associated factors, associated pastors, associate 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: ((((associated factor) OR (associated vector))) OR (associate editors)).
• Adding a wildcard symbol may retrieve word variants: ((((associated factor) or (associated vector))) or (associate editors))*.
