Perhaps you should try some spelling variations:
"supply side irrigation schemes." » "supply side irrigation scheme.", "supply side irrigation systems.", "supply saline irrigation schemes.", "supply scale irrigation schemes.", "supply under irrigation schemes."
"supply crowd integration some." » "supply grid integration some.", "supply rfid integration some.", "supply beyond integration some.", "supply crowd integration south.", "supply crowd integration soziale.", "supply crowd integration social.", "supply growth integration some.", "supply cost integration some.", "supply from integration some."

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