Perhaps you should try some spelling variations:
"supply chain integration efforts." » "supply chain international efforts.", "supply chain conservation efforts."
"Supply price innovation theory." » "Supply price innovation through.", "Supply price motivation theory.", "Supply drive innovation theory.", "Supply practice innovation theory.", "Supply service innovation theory."
supply price » supply service, supply private, supply pricing

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 price innovation theory.\") OR (\"supply chain integration efforts.\"))~".
• Removing quotes may allow a broader search: (( Supply price innovation theory. ) OR ( supply chain integration efforts. ))~.
• Adding a wildcard symbol may retrieve word variants: (("Supply price innovation theory.") OR ("supply chain integration efforts."))*.
