• If you are trying to use Boolean operators, they must be ALL CAPS: (((((irand OR ranks) OR (hand OR hard)) OR (had OR land)) OR (band OR bonds)) OR (((((grayt OR brain) OR (grantdtd OR grandtdtd)) OR grawe) OR gran) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((irand or ranks) or (hand OR hard)) or (had or land)) or (band or bonds)) or (((((grayt or brain) or (grantdtd or grandtdtd)) or grawe) or gran) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((irand or ranks) or (hand OR hard)) or (had or land)) or (band or bonds)) or (((((grayt or brain) or (grantdtd or grandtdtd)) or grawe) or gran) or graint)) counterinsurgency study ;*.
