• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sac ky) OR (sai ky)) nang ((ma hoi) or (xa hoi)). lieu ha nam thuoc xa hanh tai ca tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sac ky) OR (sai ky)) nang ((ma hoi) OR (xa hoi)). lieu ha nam thuoc xa hanh tai ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (sai ky)) nang ((ma hoi) or (xa hoi)). lieu ha nam thuoc xa hanh tai ca tren".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (sai ky)) nang ((ma hoi) or (xa hoi)). lieu ha nam thuoc xa hanh tai ca tren*.
