• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (bank OR bonds)) OR (((((rawd OR (grank OR grand)) OR grandtd) OR (draw OR grace)) OR (gran OR (grandt OR (grant OR graint)))) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (bank or bonds)) or (((((rawd or (grank OR grand)) or grandtd) or (draw or grace)) or (gran or (grandt or (grant or graint)))) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (bank or bonds)) or (((((rawd or (grank OR grand)) or grandtd) or (draw or grace)) or (gran or (grandt or (grant or graint)))) or graint)) counterinsurgency study ;*.
