• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghardtt OR harm) OR head) OR (((hardy OR (har OR hart)) OR (harsh OR bharti)) OR (hardmidm OR (hariddm OR hardiddm)))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghardtt or harm) or head) or (((hardy or (har or hart)) or (harsh or bharti)) or (hardmidm or (hariddm OR hardiddm)))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghardtt or harm) or head) or (((hardy or (har or hart)) or (harsh or bharti)) or (hardmidm or (hariddm OR hardiddm)))) or grant)) counterinsurgency study ;*.
