• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR san) OR ((hand OR hard) OR band)) OR (had OR land)) OR (bond OR bonds)) OR ((((((grant OR graft) OR ((graind OR grained) OR irand)) OR iranted) OR (grace OR raw)) OR rain) OR grains)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or san) or ((hand OR hard) or band)) or (had or land)) or (bond or bonds)) or ((((((grant or graft) or ((graind or grained) or irand)) or iranted) or (grace or raw)) or rain) or grains)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or san) or ((hand OR hard) or band)) or (had or land)) or (bond or bonds)) or ((((((grant or graft) or ((graind or grained) or irand)) or iranted) or (grace or raw)) or rain) or grains)) counterinsurgency study ;*.
