• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR (rank OR bank)) OR hard) OR (had OR land)) OR (band OR bonds)) OR (((((graind OR graind) OR ((irankstd OR ifrankstd) OR ifrankstd)) OR (grawd OR grawe)) OR grand) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or (rank or bank)) or hard) or (had or land)) or (band or bonds)) or (((((graind or graind) or ((irankstd OR ifrankstd) or ifrankstd)) or (grawd or grawe)) or grand) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or (rank or bank)) or hard) or (had or land)) or (band or bonds)) or (((((graind or graind) or ((irankstd OR ifrankstd) or ifrankstd)) or (grawd or grawe)) or grand) or grant)) counterinsurgency study ;*.
