• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu lang xa hoi. hieu va cau xuc ((va danh) or (van anh)) ki ((su viet) OR (so viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu lang xa hoi. hieu va cau xuc ((va danh) OR (van anh)) ki ((su viet) OR (so viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu lang xa hoi. hieu va cau xuc ((va danh) or (van anh)) ki ((su viet) OR (so viet))".
• Adding a wildcard symbol may retrieve word variants: te sach thu lang xa hoi. hieu va cau xuc ((va danh) or (van anh)) ki ((su viet) OR (so viet))*.
