• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (band OR bond)) OR ((((grawd OR grandtd) OR grawe) OR ((gran OR (grant OR grandt)) OR (grain OR rain))) OR (((graint OR gbraint) OR gbraint) OR grains))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (band or bond)) or ((((grawd or grandtd) or grawe) or ((gran or (grant OR grandt)) or (grain or rain))) or (((graint or gbraint) or gbraint) or grains))) counterinsurgency study ;~".
