Perhaps you should try some spelling variations:
"export change registration process." » "export change registration fees.", "export change legislation process.", "export land registration process.", "export car registration process.", "export channel registration process.", "export channels registration process.", "export share registration process."
"supporting aid conservation efforts." » "supporting land conservation efforts.", "supporting bird conservation efforts.", "supporting basic conservation efforts.", "supporting road conservation efforts.", "supporting _ conservation efforts."

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"supporting aid conservation efforts.\") OR (\"export change registration process.\"))~".
• Removing quotes may allow a broader search: (( supporting aid conservation efforts. ) OR ( export change registration process. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supporting aid conservation efforts.") OR ("export change registration process."))*.
