• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR san) OR hand) OR (had OR land)) OR (bank OR bonds)) OR ((((((grant OR (grayt OR gray)) OR grained) OR granted) OR ((grace OR grade) OR raw)) OR (iran OR iron)) OR grain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or san) or hand) or (had or land)) or (bank or bonds)) or ((((((grant or (grayt OR gray)) or grained) or granted) or ((grace or grade) or raw)) or (iran or iron)) or grain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or san) or hand) or (had or land)) or (bank or bonds)) or ((((((grant or (grayt OR gray)) or grained) or granted) or ((grace or grade) or raw)) or (iran or iron)) or grain)) counterinsurgency study ;*.
