• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ma hoi. hieu van ((cau luc) or (cam xuc)) va hang ((doi ca) OR (doi cua)) tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu van ((cau luc) OR (cam xuc)) va hang ((doi ca) OR (doi cua)) tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. hieu van ((cau luc) or (cam xuc)) va hang ((doi ca) OR (doi cua)) tren*".
