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 (air OR had)) OR (stand OR (bond OR grand))) OR land) OR ((((ghartt OR (harmt OR harttm)) OR head) OR (((hartddo OR (har OR hari)) OR ((harmtd OR hartd) OR bcharti)) OR hardmmidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (stand or (bond or grand))) or land) or ((((ghartt or (harmt or harttm)) or head) or (((hartddo or (har or hari)) or ((harmtd OR hartd) or bcharti)) or hardmmidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (stand or (bond or grand))) or land) or ((((ghartt or (harmt or harttm)) or head) or (((hartddo or (har or hari)) or ((harmtd OR hartd) or bcharti)) or hardmmidm)) or grant)) counterinsurgency study ;*.
