• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x hoi. hieu va ((((cao duc) OR (cao suc))) OR (giao duc)) gia thanh hai cua tre.
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x hoi. hieu va ((((cao duc) or (cao suc))) or (giao duc)) gia thanh hai cua tre*.
