Perhaps you should try some spelling variations:
"export prices integration process." » "export prices reintegration process.", "export prices migration process.", "export prices innovation process.", "export price integration process.", "export process integration process.", "export policies integration process.", "import prices integration process."
"supply syria irrigation scheme." » "supply syria irrigation systems.", "supply africa irrigation scheme.", "supply drip irrigation scheme.", "supply surge irrigation scheme.", "supply social irrigation scheme.", "supply sierra irrigation scheme."

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 syria irrigation scheme.\") OR (\"export prices integration process.\"))~".
• Removing quotes may allow a broader search: (( supply syria irrigation scheme. ) OR ( export prices integration process. ))~.
• Adding a wildcard symbol may retrieve word variants: (("supply syria irrigation scheme.") OR ("export prices integration process."))*.
