• If you are trying to use Boolean operators, they must be ALL CAPS: vay ((khao ky) OR (thao ky)) nang x hoi. thien van bac tu va thanh vi ((su triet) OR (cuu tre)).
• Adding a wildcard symbol may retrieve word variants: vay ((khao ky) or (thao ky)) nang x hoi. thien van bac tu va thanh vi ((su triet) or (cuu tre))*.
