• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (rank OR ranks)) OR san) OR ((band OR bank) OR land)) OR (((grantd OR (granted OR grantted)) OR migrants) OR (((grank OR graink) OR (grandk OR (graind OR graind))) OR gran))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (rank or ranks)) or san) or ((band or bank) or land)) or (((grantd or (granted OR grantted)) or migrants) or (((grank or graink) or (grandk or (graind or graind))) or gran))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (rank or ranks)) or san) or ((band or bank) or land)) or (((grantd or (granted OR grantted)) or migrants) or (((grank or graink) or (grandk or (graind or graind))) or gran))) counterinsurgency study ;*.
