• 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 (ghand OR grand))) OR (gpart OR ((((hepart OR heppart) OR art) OR gpart) OR (hard OR (cheart OR heart)))))) 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 (ghand OR grand))) or (gpart or ((((hepart or heppart) or art) or gpart) or (hard or (cheart or heart)))))) 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 (ghand OR grand))) or (gpart or ((((hepart or heppart) or art) or gpart) or (hard or (cheart or heart)))))) counterinsurgency study ;*.
