• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR ((rank OR bank) OR (((ranks OR franks) OR ((frankss OR rankss) OR (ranks OR franks))) OR franz))) OR ((hand OR had) OR stand)) OR (band OR land)) OR ((grand OR grant) OR (ghand OR ghani))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or ((rank or bank) or (((ranks or franks) or ((frankss or rankss) or (ranks or franks))) or franz))) or ((hand or had) or stand)) or (band or land)) or ((grand or grant) or (ghand OR ghani))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or ((rank or bank) or (((ranks or franks) or ((frankss or rankss) or (ranks or franks))) or franz))) or ((hand or had) or stand)) or (band or land)) or ((grand or grant) or (ghand OR ghani))) counterinsurgency study ;*.
