• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR (sand OR stand)) OR (rank OR (franks OR frans))) OR (had OR band)) OR land) OR (((irant OR (grants OR ((miirants OR miirans) OR militants))) OR gran) OR (gband OR gbank))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or (sand or stand)) or (rank or (franks OR frans))) or (had or band)) or land) or (((irant or (grants or ((miirants or miirans) or militants))) or gran) or (gband or gbank))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or (sand or stand)) or (rank or (franks OR frans))) or (had or band)) or land) or (((irant or (grants or ((miirants or miirans) or militants))) or gran) or (gband or gbank))) counterinsurgency study ;*.
