• Performing a fuzzy search may retrieve terms with similar spellings: vu sach hay lang xa hoi. thien van cam ((xuc va) or (((tuc va) OR (truc va)))) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach hay lang xa hoi. thien van cam ((xuc va) OR (((tuc va) OR (truc va)))) hanh vi cua te.
