• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hand or hard) or (had or land)) or (band or bond)) or ((((((grawd or grant) or ((grain OR gbrain) or (rain or rail))) or iranttd) or (((grawe or grace) or graw) or grow)) or grand) or main)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((hand or hard) or (had or land)) or (band or bond)) or ((((((grawd or grant) or ((grain OR gbrain) or (rain or rail))) or iranttd) or (((grawe or grace) or graw) or grow)) or grand) or main)) counterinsurgency study ;*.
