Perhaps you should try some spelling variations:
"Industrial development research period" » "Industrial development report period", "Industrial development research prior", "Industrial development research persona", "Industrial development research series"
"industrial development reform series" » "industrial development report series", "industrial development reports series", "industrial development forum series", "industrial development reform arrives", "industrial development reform studies", "industrial development reform period"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("industrial development reform series") OR ("Industrial development research period"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"industrial development reform series\") OR (\"Industrial development research period\"))*".
• Removing quotes may allow a broader search: (( industrial development reform series ) OR ( Industrial development research period ))*.
