You may be able to get more results by adjusting your search query.

• 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 grant))) OR irantd) OR grade) OR gran) OR (rain OR (grains OR ((rande OR grande) OR (rande OR grande)))))) 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 grant))) or irantd) or grade) or gran) or (rain or (grains or ((rande OR grande) or (rande OR grande)))))) 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 grant))) or irantd) or grade) or gran) or (rain or (grains or ((rande OR grande) or (rande OR grande)))))) counterinsurgency study ;*.
