Perhaps you should try some spelling variations:
"supply data integration social." » "supply data international social.", "supply trade integration social.", "supply _ integration social.", "supply data integrity social.", "supply water integration social."
"support deep irrigation schemes." » "support deep irrigation scheme.", "support deep irrigation systems.", "support drip irrigation schemes.", "support level irrigation schemes.", "support crop irrigation schemes.", "support does irrigation schemes.", "support them irrigation schemes.", "support data irrigation schemes."

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 data integration social.\") OR (\"support deep irrigation schemes.\"))~".
• Removing quotes may allow a broader search: (( supply data integration social. ) OR ( support deep irrigation schemes. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply data integration social.") OR ("support deep irrigation schemes."))*.
