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: ((((rand OR rank) OR (sand OR (hand OR hard))) OR ((bond OR bank) OR land)) OR (((graind OR ((ggain OR grain) OR rain)) OR (gffranks OR (gran OR grand))) OR ((had OR cham) OR ghana))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or rank) or (sand or (hand or hard))) or ((bond or bank) or land)) or (((graind or ((ggain OR grain) or rain)) or (gffranks or (gran or grand))) or ((had or cham) or ghana))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or rank) or (sand or (hand or hard))) or ((bond or bank) or land)) or (((graind or ((ggain OR grain) or rain)) or (gffranks or (gran or grand))) or ((had or cham) or ghana))) counterinsurgency study ;*.
