• If you are trying to use Boolean operators, they must be ALL CAPS: (((((irand OR san) OR hard) OR (had OR land)) OR (bank OR bond)) OR ((((((((grande OR gray) OR irand) OR grant) OR ggain) OR grantstd) OR ((grawe OR grade) OR raw)) OR gran) OR brain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((irand or san) or hard) or (had or land)) or (bank or bond)) or ((((((((grande or gray) or irand) or grant) or ggain) or grantstd) or ((grawe OR grade) or raw)) or gran) or brain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((irand or san) or hard) or (had or land)) or (bank or bond)) or ((((((((grande or gray) or irand) or grant) or ggain) or grantstd) or ((grawe OR grade) or raw)) or gran) or brain)) counterinsurgency study ;*.
