• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x hoi. hieu vien cac ((((duc ban) OR (dua ban))) OR (duc tan)) thanh vai cuu tre.
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x hoi. hieu vien cac ((((duc ban) or (dua ban))) or (duc tan)) thanh vai cuu tre*.
