• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky dang ma hoi. hieu ((vu cham) OR (vu kham)) duc tan thanh va ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky dang ma hoi. hieu ((vu cham) OR (vu kham)) duc tan thanh va ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky dang ma hoi. hieu ((vu cham) OR (vu kham)) duc tan thanh va ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: tu san ky dang ma hoi. hieu ((vu cham) OR (vu kham)) duc tan thanh va ((cua te) or (cua tu))*.
