• Performing a fuzzy search may retrieve terms with similar spellings: vu sach v sang ma hoi. hieu ve ((lam truoc) OR (lam truong)) ((va hanh) or (va thanh)) tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach v sang ma hoi. hieu ve ((lam truoc) OR (lam truong)) ((va hanh) OR (va thanh)) tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach v sang ma hoi. hieu ve ((lam truoc) OR (lam truong)) ((va hanh) or (va thanh)) tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: vu sach v sang ma hoi. hieu ve ((lam truoc) OR (lam truong)) ((va hanh) or (va thanh)) tai cuu tre*.
