• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (rank OR (franks OR frank))) OR (hand OR band)) OR land) OR (((irand OR (grantees OR migraints)) OR (gbank OR gran)) OR (irand OR gbank))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (rank or (franks OR frank))) or (hand or band)) or land) or (((irand or (grantees or migraints)) or (gbank or gran)) or (irand or gbank))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (rank or (franks OR frank))) or (hand or band)) or land) or (((irand or (grantees or migraints)) or (gbank or gran)) or (irand or gbank))) counterinsurgency study ;*.
