• If you are trying to use Boolean operators, they must be ALL CAPS: (((((sand OR san) OR hand) OR (had OR land)) OR (band OR bond)) OR ((((((gray OR (grains OR gmaints)) OR gain) OR grainsstd) OR (drawe OR graw)) OR grain) OR ((graint OR braint) OR grant))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((sand OR san) or hand) or (had or land)) or (band or bond)) or ((((((gray or (grains or gmaints)) or gain) or grainsstd) or (drawe or graw)) or grain) or ((graint or braint) or grant))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((sand OR san) or hand) or (had or land)) or (band or bond)) or ((((((gray or (grains or gmaints)) or gain) or grainsstd) or (drawe or graw)) or grain) or ((graint or braint) or grant))) counterinsurgency study ;*.
