• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ((xay hoi) OR (tay hoi)). hieu ((ve chat) or (van chat)) xuc va thanh van luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((xay hoi) OR (tay hoi)). hieu ((ve chat) OR (van chat)) xuc va thanh van luu tre.
