Perhaps you should try some spelling variations:
"supply count integrating countries." » "supply count importing countries.", "supply count immigration countries.", "supply count integrating culture.", "supply china integrating countries.", "supply congo integrating countries.", "supply event integrating countries.", "supply cost integrating countries.", "supply costs integrating countries."
"supply 4 conservation efforts." » "supply _ conservation efforts.", "supply land conservation efforts.", "supply fuel conservation efforts.", "supply a conservation efforts.", "supply 3 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: "((\"supply 4 conservation efforts.\") OR (\"supply count integrating countries.\"))~".
• Removing quotes may allow a broader search: (( supply 4 conservation efforts. ) OR ( supply count integrating countries. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply 4 conservation efforts.") OR ("supply count integrating countries."))*.
