• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((ty nang) or (ty xang)) x hoi. hieu ((qua pham) OR (quy pham)) duc tan banh d cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty nang) OR (ty xang)) x hoi. hieu ((qua pham) OR (quy pham)) duc tan banh d cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty nang) or (ty xang)) x hoi. hieu ((qua pham) OR (quy pham)) duc tan banh d cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty nang) or (ty xang)) x hoi. hieu ((qua pham) OR (quy pham)) duc tan banh d cua tre*.
