Perhaps you should try some spelling variations:
integration schemes » irrigation schemes, integration some, integration theories
integration efforts » international efforts, conservation efforts
chain integration » trade integration, data integration, grid integration
fare integration » market integration, trade integration, data integration
export fare » export share, export base, export more

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( supply chain integration schemes. ) OR ( export fare integration efforts. ))~.
• Adding a wildcard symbol may retrieve word variants: (( supply chain integration schemes. ) or ( export fare integration efforts. ))*.
