Perhaps you should try some spelling variations:
"supply american integration schemes." » "supply numerical integration schemes.", "supply vertical integration schemes.", "supply asian integration schemes.", "supply american irrigation schemes.", "supply american integration some.", "supply american integration theories."
"supply side integration series." » "supply side integration theories.", "supply side integrating services.", "supply side integration social.", "supply trade integration series.", "supply asian integration series.", "supply grid integration series."

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