Perhaps you should try some spelling variations:
"e development policies." » "e development policy.", "e development projects.", "sme development policies.", "mine development policies.", "site development policies."
"e development studies." » "e development series.", "e development services.", "e development strategies.", "sme development studies.", "mine development studies.", "site development studies."
"e development process." » "e development projects.", "e development programs.", "sme development process.", "mine development process.", "site development process."

Try widening your search to All Fields.

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

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