• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (band OR bonds)) OR ((((grayd OR (grandtd OR ggsandtd)) OR ((grawe OR rawe) OR grace)) OR (grand OR graw)) OR ((braint OR raint) OR grain))) 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 bonds)) or ((((grayd or (grandtd or ggsandtd)) or ((grawe OR rawe) or grace)) or (grand or graw)) or ((braint or raint) or grain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (band or bonds)) or ((((grayd or (grandtd or ggsandtd)) or ((grawe OR rawe) or grace)) or (grand or graw)) or ((braint or raint) or grain))) counterinsurgency study ;*.
