• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR ((grant OR irant) OR grandttd)) OR hard) OR (had OR land)) OR (bond OR bonds)) OR (((((((grants OR grantts) OR grawdtts) OR trained) OR grandtd) OR grawe) OR gran) OR grain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or ((grant OR irant) or grandttd)) or hard) or (had or land)) or (bond or bonds)) or (((((((grants or grantts) or grawdtts) or trained) or grandtd) or grawe) or gran) or grain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or ((grant OR irant) or grandttd)) or hard) or (had or land)) or (bond or bonds)) or (((((((grants or grantts) or grawdtts) or trained) or grandtd) or grawe) or gran) or grain)) counterinsurgency study ;*.
