Perhaps you should try some spelling variations:
"Industrial development department period" » "Industrial development partners period", "Industrial development government period", "Industrial government department period", "Industrial development repayment period", "Industrial development deferment period", "Industrial development repayment periods"
"industrial development rest period" » "industrial development west period", "industrial development best period", "industrial development forest period", "industrial development rest periods", "industrial development test period", "industrial development last period"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"Industrial development department period\") OR (\"industrial development rest period\"))~".
• Removing quotes may allow a broader search: (( Industrial development department period ) OR ( industrial development rest period ))~.
• Adding a wildcard symbol may retrieve word variants: (("Industrial development department period") OR ("industrial development rest period"))*.
