• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai ((cua tu) OR (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky lang ha hoi. hieu ((va cam) OR (va cham)) luc va hanh tai ((cua tu) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai ((cua tu) OR (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: te sai ky lang ha hoi. hieu ((va cam) or (va cham)) luc va hanh tai ((cua tu) OR (cua tuc))*.
