• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR sand) OR (bank OR had)) OR land) OR bonds) OR ((grank OR (band OR grand)) OR ((gpart OR ipart) OR (((hepart OR art) OR (gpart OR ipart)) OR (hard OR (cheart OR cheat)))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or sand) or (bank or had)) or land) or bonds) or ((grank or (band or grand)) or ((gpart OR ipart) or (((hepart or art) or (gpart OR ipart)) or (hard or (cheart or cheat)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or sand) or (bank or had)) or land) or bonds) or ((grank or (band or grand)) or ((gpart OR ipart) or (((hepart or art) or (gpart OR ipart)) or (hard or (cheart or cheat)))))) counterinsurgency study ;*.
