Perhaps you should try some spelling variations:
decision patterns » decision pattern, division patterns, dentition patterns
policy decision » policy decisions, policy design
decision takers » decision makers, decision maker's, decision maker

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: (( off policy decision patterns ) OR ( off policy decision takers )).
• Adding a wildcard symbol may retrieve word variants: (( off policy decision patterns ) or ( off policy decision takers ))*.
