Perhaps you should try some spelling variations:
"administrative discretions" » "administrative discretion", "administrative directions", "administrative functions"
"administrative decisions" » "administrative decision", "administration decision", "administrative functions"
"administrative region" » "administrative regional"

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: (("administrative discretions") OR ((("administrative decisions") OR ("administrative region"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"administrative discretions\") or (((\"administrative decisions\") OR (\"administrative region\"))))*".
• Removing quotes may allow a broader search: (( administrative discretions ) or ((( administrative decisions ) OR ( administrative region ))))*.
