• Performing a fuzzy search may retrieve terms with similar spellings: vu hai ky tang van hoi. hieu ((ve cac) OR (vien cac)) xuc va ((dan de) or (dan den)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu hai ky tang van hoi. hieu ((ve cac) OR (vien cac)) xuc va ((dan de) OR (dan den)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu hai ky tang van hoi. hieu ((ve cac) OR (vien cac)) xuc va ((dan de) or (dan den)) cua tre*".
