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