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