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