Perhaps you should try some spelling variations:
"export change migration process." » "export change registration process.", "export change mitigation process.", "export managed migration process.", "export change education process.", "export channel migration process.", "export channels migration process.", "export share migration process."
"supporting ndc conservation efforts." » "supporting land conservation efforts.", "supporting _ conservation efforts.", "supporting aid conservation efforts.", "supporting job conservation efforts.", "support ndc conservation efforts."

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("supporting ndc conservation efforts.") OR ("export change migration process."))~.
• Removing quotes may allow a broader search: (( supporting ndc conservation efforts. ) or ( export change migration process. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supporting ndc conservation efforts.") or ("export change migration process."))*.
