• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) or (sai ky)) ((tang ma) OR (tang van)) hoi. hieu van cam tuc va danh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sai ky)) ((tang ma) OR (tang van)) hoi. hieu van cam tuc va danh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sai ky)) ((tang ma) OR (tang van)) hoi. hieu van cam tuc va danh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sai ky)) ((tang ma) OR (tang van)) hoi. hieu van cam tuc va danh vai cuu tre*.
