• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or (sand or (hand or (band OR bond)))) or (bank or had)) or land) or bonds) or (((grank or grand) or (gband or gbond)) or (chpart or (((hpart or art) or chpart) or (harm or (cheart or chepart)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or (sand or (hand or (band OR bond)))) or (bank or had)) or land) or bonds) or (((grank or grand) or (gband or gbond)) or (chpart or (((hpart or art) or chpart) or (harm or (cheart or chepart)))))) counterinsurgency study ;*.
