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