• Performing a fuzzy search may retrieve terms with similar spellings: toc sac ky ((dang ha) or (long ha)) hoi. hieu viec cac ((tuc tang) OR (duc thang)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky ((dang ha) OR (long ha)) hoi. hieu viec cac ((tuc tang) OR (duc thang)) hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky ((dang ha) or (long ha)) hoi. hieu viec cac ((tuc tang) OR (duc thang)) hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: toc sac ky ((dang ha) or (long ha)) hoi. hieu viec cac ((tuc tang) OR (duc thang)) hanh vai cua te*.
