Perhaps you should try some spelling variations:
integration efforts » international efforts, conservation efforts
importing countries » exporting countries, importing country
crowd importing » food importing, clocks importing
supply crowd » supply growth, supply cost, supply from
supply grid » supply great, support grid

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 crowd importing countries. ))~".
• Adding a wildcard symbol may retrieve word variants: (( supply grid integration efforts. ) OR ( supply crowd importing countries. ))*.
