• If you are trying to use Boolean operators, they must be ALL CAPS: ((((sand OR san) OR (hand OR land)) OR (band OR (bond OR bonds))) OR (((trand OR ((grayd OR grand) OR ray)) OR ((gran OR (grain OR brain)) OR (rank OR (ranks OR frank)))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((sand or san) or (hand or land)) or (band or (bond or bonds))) or (((trand or ((grayd OR grand) or ray)) or ((gran or (grain or brain)) or (rank or (ranks or frank)))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((sand or san) or (hand or land)) or (band or (bond or bonds))) or (((trand or ((grayd OR grand) or ray)) or ((gran or (grain or brain)) or (rank or (ranks or frank)))) or grant)) counterinsurgency study ;*.
