• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (bond OR bonds)) OR ((((((grants OR migrants) OR (grank OR frank)) OR (graydtd OR grantsed)) OR graw) OR (grand OR ghand)) OR (((grain OR ggain) OR gmain) OR rain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (bond or bonds)) or ((((((grants OR migrants) or (grank or frank)) or (graydtd or grantsed)) or graw) or (grand or ghand)) or (((grain or ggain) or gmain) or rain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (bond or bonds)) or ((((((grants OR migrants) or (grank or frank)) or (graydtd or grantsed)) or graw) or (grand or ghand)) or (((grain or ggain) or gmain) or rain))) counterinsurgency study ;*.
