Perhaps you should try some spelling variations:
associated vectors » associated vector, associated factors, associated receptors
associated pastors » associated factors, associated pairs, associated operators
associate factor » associated factors, associated vector, associate director

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 vectors) OR (associated pastors))) OR (associate factor)).
• Adding a wildcard symbol may retrieve word variants: ((((associated vectors) or (associated pastors))) or (associate factor))*.
