• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR ((sand OR san) OR stand)) OR (bank OR had)) OR land) OR bond) OR (((grank OR rank) OR grand) OR (ghard OR (((haro OR hero) OR (gheart OR (hart OR part))) OR (hari OR chart))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or ((sand OR san) or stand)) or (bank or had)) or land) or bond) or (((grank or rank) or grand) or (ghard or (((haro or hero) or (gheart or (hart or part))) or (hari or chart))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or ((sand OR san) or stand)) or (bank or had)) or land) or bond) or (((grank or rank) or grand) or (ghard or (((haro or hero) or (gheart or (hart or part))) or (hari or chart))))) counterinsurgency study ;*.
