• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((sach xa) OR (sach nha)) moi gioi lam tdong tin ) OR ( tu sach bac ve giao con hong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu ((sach xa) or (sach nha)) moi gioi lam tdong tin ) or ( tu sach bac ve giao con hong tin ))*.
