• If you are trying to use Boolean operators, they must be ALL CAPS: (("its colonization history") OR ((("jews communication iraq") OR ("lea's communication iraq"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"its colonization history\") or (((\"jews communication iraq\") OR (\"lea's communication iraq\"))))~".
• Removing quotes may allow a broader search: (( its colonization history ) or ((( jews communication iraq ) OR ( lea's communication iraq ))))~.
• Adding a wildcard symbol may retrieve word variants: (("its colonization history") or ((("jews communication iraq") OR ("lea's communication iraq"))))*.
