"support grant integration efforts." » "support grant international efforts.", "support grant conservation efforts.", "support migrant integration efforts.", "support migrants integration efforts.", "support statt integration efforts."
"support crop irrigation scheme." » "support crop irrigation systems.", "support drip irrigation scheme.", "support scale irrigation scheme.", "support canal irrigation scheme.", "support crops irrigation scheme.", "support cross irrigation scheme.", "support across irrigation scheme."

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: (("support crop irrigation scheme.") OR ("support grant integration efforts."))~.
• Removing quotes may allow a broader search: (( support crop irrigation scheme. ) or ( support grant integration efforts. ))~.
• Adding a wildcard symbol may retrieve word variants: (("support crop irrigation scheme.") or ("support grant integration efforts."))*.
