• 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 (((((grand OR grant) OR gsandtd) OR (grave OR (graw OR grow))) OR ((gran OR grain) OR raw)) OR ((braint OR (rain OR gain)) OR brain))) 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 (((((grand OR grant) or gsandtd) or (grave or (graw or grow))) or ((gran or grain) or raw)) or ((braint or (rain or gain)) or brain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (bond or bonds)) or (((((grand OR grant) or gsandtd) or (grave or (graw or grow))) or ((gran or grain) or raw)) or ((braint or (rain or gain)) or brain))) counterinsurgency study ;*.
