• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((rand OR grand) OR san) OR hand) OR (had OR land)) OR (band OR bond)) OR ((((((irand OR (graints OR grandts)) OR ggaind) OR grandtstd) OR (grave OR graw)) OR gran) OR (rain OR main))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((rand OR grand) or san) or hand) or (had or land)) or (band or bond)) or ((((((irand or (graints or grandts)) or ggaind) or grandtstd) or (grave or graw)) or gran) or (rain or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((rand OR grand) or san) or hand) or (had or land)) or (band or bond)) or ((((((irand or (graints or grandts)) or ggaind) or grandtstd) or (grave or graw)) or gran) or (rain or main))) counterinsurgency study ;*.
