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

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