• If you are trying to use Boolean operators, they must be ALL CAPS: (((((grand OR (rank OR bank)) OR hard) OR (had OR land)) OR (band OR bonds)) OR (((((((irant OR (irani OR iraqi)) OR ghani) OR (graind OR grain)) OR iranktd) OR grade) OR gran) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((grand or (rank OR bank)) or hard) or (had or land)) or (band or bonds)) or (((((((irant or (irani or iraqi)) or ghani) or (graind or grain)) or iranktd) or grade) or gran) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((grand or (rank OR bank)) or hard) or (had or land)) or (band or bonds)) or (((((((irant or (irani or iraqi)) or ghani) or (graind or grain)) or iranktd) or grade) or gran) or graint)) counterinsurgency study ;*.
