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