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