• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (band OR bonds)) OR (((((grandt OR irank) OR (granddtd OR ((grantsed OR graintsed) OR (grants OR graints)))) OR raw) OR gran) OR (gbrain OR (rain OR main)))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (band or bonds)) or (((((grandt or irank) or (granddtd or ((grantsed or graintsed) or (grants or graints)))) or raw) or gran) or (gbrain or (rain OR main)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (band or bonds)) or (((((grandt or irank) or (granddtd or ((grantsed or graintsed) or (grants or graints)))) or raw) or gran) or (gbrain or (rain OR main)))) counterinsurgency study ;*.
