• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky van xay hoi. hieu van cam ((xuc va) OR (duc va)) dan vat ((cuu tre) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky van xay hoi. hieu van cam ((xuc va) OR (duc va)) dan vat ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky van xay hoi. hieu van cam ((xuc va) OR (duc va)) dan vat ((cuu tre) or (cau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach ky van xay hoi. hieu van cam ((xuc va) OR (duc va)) dan vat ((cuu tre) or (cau tren))*.
