• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky dang mau hoi. hieu ve cam luc van hanh ((bai cua) OR (((lai cua) OR (hai cua)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky dang mau hoi. hieu ve cam luc van hanh ((bai cua) or (((lai cua) OR (hai cua)))) tre~".
• Adding a wildcard symbol may retrieve word variants: toc sac ky dang mau hoi. hieu ve cam luc van hanh ((bai cua) or (((lai cua) OR (hai cua)))) tre*.
