Perhaps you should try some spelling variations:
"administrative information" » "administration information", "administration informatique", "administrative regulation"
"administrative absorption" » "administrative allocation", "administrative discretion", "administrative discretions"
"administrative innovation" » "administrative regulation", "administrative organization", "administrative organisation"

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 absorption") OR ((("administrative information") OR ("administrative innovation")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"administrative absorption\") or (((\"administrative information\") OR (\"administrative innovation\"))))".
• Removing quotes may allow a broader search: (( administrative absorption ) or ((( administrative information ) OR ( administrative innovation )))).
• Adding a wildcard symbol may retrieve word variants: (("administrative absorption") or ((("administrative information") OR ("administrative innovation"))))*.
