Perhaps you should try some spelling variations:
"supply grid integration efforts." » "supply grid international efforts.", "supply grid conservation efforts.", "supply crowd integration efforts.", "supply great integration efforts.", "support grid integration efforts."
"supply nepal integration schemes." » "supply nepal integration schengen.", "supply nepal irrigation schemes.", "supply nepal integration regimes.", "supply neural integration schemes.", "supply legal integration schemes.", "supply modal integration schemes.", "supply annual integration schemes.", "supply needs integration schemes."

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 grid integration efforts.\") OR (\"supply nepal integration schemes.\"))~".
• Removing quotes may allow a broader search: (( supply grid integration efforts. ) OR ( supply nepal integration schemes. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply grid integration efforts.") OR ("supply nepal integration schemes."))*.
