• If you are trying to use Boolean operators, they must be ALL CAPS: ((((san OR hard) OR (had OR land)) OR (bank OR bonds)) OR (((((trained OR (irand OR (grand OR irand))) OR granttd) OR grawe) OR gran) OR (grain OR (grains OR (irande OR (grande OR grade)))))) 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 bonds)) or (((((trained or (irand or (grand OR irand))) or granttd) or grawe) or gran) or (grain or (grains or (irande or (grande or grade)))))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((san or hard) or (had or land)) or (bank or bonds)) or (((((trained or (irand or (grand OR irand))) or granttd) or grawe) or gran) or (grain or (grains or (irande or (grande or grade)))))) counterinsurgency study ;*.
