• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky lang xa hoi. hieu ((vu cham) OR (vu kham)) xuc va han dau ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky lang xa hoi. hieu ((vu cham) OR (vu kham)) xuc va han dau ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky lang xa hoi. hieu ((vu cham) OR (vu kham)) xuc va han dau ((cuu tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sai ky lang xa hoi. hieu ((vu cham) OR (vu kham)) xuc va han dau ((cuu tre) or (cau treo))*.
