• If you are trying to use Boolean operators, they must be ALL CAPS: ((((san OR hard) OR (had OR land)) OR ((band OR bank) OR bonds)) OR (((((((rain OR brain) OR (iranted OR (graint OR railt))) OR (gray OR draft)) OR irantdtd) OR trade) OR (gran OR gain)) OR (rains OR amains))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((san or hard) or (had or land)) or ((band or bank) or bonds)) or (((((((rain OR brain) or (iranted or (graint or railt))) or (gray or draft)) or irantdtd) or trade) or (gran or gain)) or (rains or amains))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((san or hard) or (had or land)) or ((band or bank) or bonds)) or (((((((rain OR brain) or (iranted or (graint or railt))) or (gray or draft)) or irantdtd) or trade) or (gran or gain)) or (rains or amains))) counterinsurgency study ;*.
