Perhaps you should try some spelling variations:
"mine development projects." » "mine development policy.", "asian development projects.", "trade development projects.", "based development projects."
"sme development projects." » "sme development policy.", "a development projects.", "asian development projects.", "trade development projects."
"_ development process." » "_ development programs.", "_ development policies."

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

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