• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR rank) OR hard) OR (had OR land)) OR (band OR (bond OR bonds))) OR (((((((grand OR gsand) OR ghani) OR (graind OR grains)) OR iranktd) OR grad) OR gran) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or rank) or hard) or (had or land)) or (band or (bond or bonds))) or (((((((grand OR gsand) or ghani) or (graind or grains)) or iranktd) or grad) or gran) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or rank) or hard) or (had or land)) or (band or (bond or bonds))) or (((((((grand OR gsand) or ghani) or (graind or grains)) or iranktd) or grad) or gran) or graint)) counterinsurgency study ;*.
