• 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 (((((grant OR frank) OR (((granddtd OR ghanddtd) OR iranddtd) OR grantssed)) OR raw) OR grand) OR ((gmain OR grain) OR (rain OR gains)))) 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 (((((grant or frank) or (((granddtd OR ghanddtd) or iranddtd) or grantssed)) or raw) or grand) or ((gmain or grain) or (rain or gains)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (band or bonds)) or (((((grant or frank) or (((granddtd OR ghanddtd) or iranddtd) or grantssed)) or raw) or grand) or ((gmain or grain) or (rain or gains)))) counterinsurgency study ;*.
