• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (bank OR bonds)) OR (((((graint OR (rains OR brains)) OR ((graintdtd OR gbraintdtd) OR (gpainted OR rainted))) OR (graw OR raw)) OR gran) OR (graint OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (bank or bonds)) or (((((graint or (rains or brains)) or ((graintdtd or gbraintdtd) or (gpainted or rainted))) or (graw OR raw)) or gran) or (graint or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (bank or bonds)) or (((((graint or (rains or brains)) or ((graintdtd or gbraintdtd) or (gpainted or rainted))) or (graw OR raw)) or gran) or (graint or rain))) counterinsurgency study ;*.
