• The words AND, OR and NOT may confuse the search; try adding quotes: "((((sand or hard) or (had or land)) or ((band or bond) or bonds)) or ((((((gray or grantts) or ((rain OR main) or bmain)) or granddttd) or (grade or raw)) or grant) or (gbraint or granddt))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((sand or hard) or (had or land)) or ((band or bond) or bonds)) or ((((((gray or grantts) or ((rain OR main) or bmain)) or granddttd) or (grade or raw)) or grant) or (gbraint or granddt))) counterinsurgency study ;*.
