• Performing a fuzzy search may retrieve terms with similar spellings: ((co sach) OR (bo sach)) ty nang xa hoi. hieu ((qua cham) or (qua hai)) xuc va dinh tri cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((co sach) OR (bo sach)) ty nang xa hoi. hieu ((qua cham) OR (qua hai)) xuc va dinh tri cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((co sach) OR (bo sach)) ty nang xa hoi. hieu ((qua cham) or (qua hai)) xuc va dinh tri cua te*".
