• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((thu lang) or (thu huong)) van hoa. hieu lua dao ((xuc van) OR (vuc van)) doanh dan cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((thu lang) OR (thu huong)) van hoa. hieu lua dao ((xuc van) OR (vuc van)) doanh dan cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((thu lang) or (thu huong)) van hoa. hieu lua dao ((xuc van) OR (vuc van)) doanh dan cua tu".
• Adding a wildcard symbol may retrieve word variants: te sach ((thu lang) or (thu huong)) van hoa. hieu lua dao ((xuc van) OR (vuc van)) doanh dan cua tu*.
