• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (hand or hard)) or (had or land)) or (bond or bonds)) or (((((san or gmained) or ggbandtd) or (grawe or growe)) or (san or (graw OR grow))) or ((brazil or brain) or (rain or bgain)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand or hard)) or (had or land)) or (bond or bonds)) or (((((san or gmained) or ggbandtd) or (grawe or growe)) or (san or (graw OR grow))) or ((brazil or brain) or (rain or bgain)))) counterinsurgency study ;*.
