• If you are trying to use Boolean operators, they must be ALL CAPS: ((((grant OR (rank OR banks)) OR sand) OR ((band OR bank) OR land)) OR ((grandted OR (grantted OR graintted)) OR ((gfrank OR ((irand OR (granttdk OR iranttdk)) OR granddk)) OR gran))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((grant or (rank or banks)) or sand) or ((band or bank) or land)) or ((grandted or (grantted or graintted)) or ((gfrank or ((irand or (granttdk OR iranttdk)) or granddk)) or gran))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((grant or (rank or banks)) or sand) or ((band or bank) or land)) or ((grandted or (grantted or graintted)) or ((gfrank or ((irand or (granttdk OR iranttdk)) or granddk)) or gran))) counterinsurgency study ;*.
