• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (((band OR bank) OR bond) OR bonds)) OR ((((((grant OR graint) OR gained) OR grantdtd) OR ((grave OR grade) OR graw)) OR gran) OR (grains OR geraint))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (((band or bank) or bond) or bonds)) or ((((((grant or graint) or gained) or grantdtd) or ((grave OR grade) or graw)) or gran) or (grains or geraint))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (((band or bank) or bond) or bonds)) or ((((((grant or graint) or gained) or grantdtd) or ((grave OR grade) or graw)) or gran) or (grains or geraint))) counterinsurgency study ;*.
