• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (bank OR bonds)) OR (((((gbraint OR granted) OR granktd) OR rice) OR (grand OR grow)) OR ((((braint OR bgaint) OR bmain) OR gains) 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 (bank or bonds)) or (((((gbraint or granted) or granktd) or rice) or (grand or grow)) or ((((braint OR bgaint) or bmain) or gains) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bank or bonds)) or (((((gbraint or granted) or granktd) or rice) or (grand or grow)) or ((((braint OR bgaint) or bmain) or gains) or rain))) counterinsurgency study ;*.
