Perhaps you should try some spelling variations:
"initial investment policies series" » "initial investment policy series", "initial government policies series", "initial development policies series", "national investment policies series", "capital investment policies series"
"industrial development cases studies" » "industrial development case studies", "industrial development charges studies", "industrial development crisis studies", "industrial development cost studies", "industrial development use studies"

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

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