• If you are trying to use Boolean operators, they must be ALL CAPS: (((((sand OR frank) OR hand) OR (had OR land)) OR (bond OR bonds)) OR (((((grand OR grant) OR gfranktd) OR (((grows OR grower) OR grown) OR (graw OR draw))) OR gran) OR geraint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((sand or frank) or hand) or (had or land)) or (bond or bonds)) or (((((grand OR grant) or gfranktd) or (((grows or grower) or grown) or (graw or draw))) or gran) or geraint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((sand or frank) or hand) or (had or land)) or (bond or bonds)) or (((((grand OR grant) or gfranktd) or (((grows or grower) or grown) or (graw or draw))) or gran) or geraint)) counterinsurgency study ;*.
