• If you are trying to use Boolean operators, they must be ALL CAPS: ((((san OR hard) OR (had OR land)) OR (bank OR (bond OR bonds))) OR (((((graind OR (irand OR grand)) OR grandtd) OR grawe) OR gran) OR (grain OR (grains OR (irande OR rande))))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((san or hard) or (had or land)) or (bank or (bond or bonds))) or (((((graind or (irand or grand)) or grandtd) or grawe) or gran) or (grain or (grains or (irande OR rande))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((san or hard) or (had or land)) or (bank or (bond or bonds))) or (((((graind or (irand or grand)) or grandtd) or grawe) or gran) or (grain or (grains or (irande OR rande))))) counterinsurgency study ;*.
