• If you are trying to use Boolean operators, they must be ALL CAPS: ((((sand OR hard) OR (had OR land)) OR (bank OR bonds)) OR ((((((((grand OR grayd) OR (grants OR grantts)) OR grain) OR gmaind) OR (grantttd OR irantttd)) OR (graw OR draw)) OR gran) OR rain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((sand or hard) or (had or land)) or (bank or bonds)) or ((((((((grand OR grayd) or (grants or grantts)) or grain) or gmaind) or (grantttd or irantttd)) or (graw or draw)) or gran) or rain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((sand or hard) or (had or land)) or (bank or bonds)) or ((((((((grand OR grayd) or (grants or grantts)) or grain) or gmaind) or (grantttd or irantttd)) or (graw or draw)) or gran) or rain)) counterinsurgency study ;*.
