• If you are trying to use Boolean operators, they must be ALL CAPS: ((((grand OR hand) OR (had OR land)) OR (band OR bonds)) OR (((((irani OR (irank OR ranks)) OR (ggbrainddtd OR (strained OR gsandts))) OR raw) OR (gran OR (graind OR ggaind))) OR (gbgain OR (rain OR main)))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grand or hand) or (had or land)) or (band or bonds)) or (((((irani or (irank or ranks)) or (ggbrainddtd or (strained or gsandts))) or raw) or (gran or (graind or ggaind))) or (gbgain or (rain OR main)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grand or hand) or (had or land)) or (band or bonds)) or (((((irani or (irank or ranks)) or (ggbrainddtd or (strained or gsandts))) or raw) or (gran or (graind or ggaind))) or (gbgain or (rain OR main)))) counterinsurgency study ;*.
