• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (san OR (band OR grand))) OR land) OR (((((chart OR chartt) OR gharmm) OR heat) OR (((heart OR har) OR ((harmi OR (hard OR harid)) OR chartts)) OR hairm)) OR (grant OR grants))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (san or (band or grand))) or land) or (((((chart or chartt) or gharmm) or heat) or (((heart or har) or ((harmi or (hard OR harid)) or chartts)) or hairm)) or (grant or grants))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (san or (band or grand))) or land) or (((((chart or chartt) or gharmm) or heat) or (((heart or har) or ((harmi or (hard OR harid)) or chartts)) or hairm)) or (grant or grants))) counterinsurgency study ;*.
