• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"costs agriculture iran\") or (((\"crop agriculture israel\") OR (\"scale agriculture israel\"))))~".
• Removing quotes may allow a broader search: (( costs agriculture iran ) or ((( crop agriculture israel ) OR ( scale agriculture israel ))))~.
• Adding a wildcard symbol may retrieve word variants: (("costs agriculture iran") or ((("crop agriculture israel") OR ("scale agriculture israel"))))*.
