Perhaps you should try some spelling variations:
"_ government policies." » "_ government policy."
"a development series." » "a development services.", "a development agencies.", "a development africa.", "_ development series.", "clean development series.", "city development series."
"asian development series." » "asian development services.", "asian development agencies.", "asian development africa.", "human development series.", "urban development series.", "clean development series."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("a development series.") OR ("asian development series."))) or ("_ government policies."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a development series.") OR ("asian development series."))) OR ("_ government policies."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a development series.\") OR (\"asian development series.\"))) or (\"_ government policies.\"))*".
• Removing quotes may allow a broader search: (((( a development series. ) OR ( asian development series. ))) or ( _ government policies. ))*.
