• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hairmmdmd OR had)) OR (stand OR (bank OR grant))) OR land) OR ((((ghartdtt OR gharmm) OR head) OR ((((harmt OR hart) OR (har OR fair)) OR (harim OR (harmti OR harati))) OR hairm)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hairmmdmd or had)) or (stand or (bank or grant))) or land) or ((((ghartdtt or gharmm) or head) or ((((harmt or hart) or (har or fair)) or (harim or (harmti OR harati))) or hairm)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hairmmdmd or had)) or (stand or (bank or grant))) or land) or ((((ghartdtt or gharmm) or head) or ((((harmt or hart) or (har or fair)) or (harim or (harmti OR harati))) or hairm)) or grants)) counterinsurgency study ;*.
