• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (bond OR bonds)) OR ((((((geraint OR gemaint) OR irank) OR (ggranddtd OR (grained OR (grants OR migmaints)))) OR raw) OR gran) OR ((gbrain OR (brain OR bmain)) OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (bond or bonds)) or ((((((geraint or gemaint) or irank) or (ggranddtd or (grained or (grants or migmaints)))) or raw) or gran) or ((gbrain or (brain OR bmain)) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bond or bonds)) or ((((((geraint or gemaint) or irank) or (ggranddtd or (grained or (grants or migmaints)))) or raw) or gran) or ((gbrain or (brain OR bmain)) or rain))) counterinsurgency study ;*.
