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