You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghartt OR (hartd OR hardly)) OR head) OR (((harddo OR (har OR harmi)) OR (heart OR bharmti)) OR (harmmidm OR harmmmidm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or (hartd or hardly)) or head) or (((harddo or (har or harmi)) or (heart or bharmti)) or (harmmidm OR harmmmidm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or (hartd or hardly)) or head) or (((harddo or (har or harmi)) or (heart or bharmti)) or (harmmidm OR harmmmidm))) or grant)) counterinsurgency study ;*.
