• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hand OR (rank OR (ranks OR banks))) OR (sand OR stand)) OR ((band OR bank) OR land)) OR (grand OR (((grank OR irans) OR frank) OR (gran OR ((graint OR (grawt OR grant)) OR (grawt OR grant)))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hand or (rank or (ranks or banks))) or (sand or stand)) or ((band or bank) or land)) or (grand or (((grank or irans) or frank) or (gran or ((graint or (grawt OR grant)) or (grawt OR grant)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((hand or (rank or (ranks or banks))) or (sand or stand)) or ((band or bank) or land)) or (grand or (((grank or irans) or frank) or (gran or ((graint or (grawt OR grant)) or (grawt OR grant)))))) counterinsurgency study ;*.
