• Performing a fuzzy search may retrieve terms with similar spellings: ((te bai) OR (te ban)) ky lang xa hoi. hieu va cham luc va ((hanh tai) or (thanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te bai) OR (te ban)) ky lang xa hoi. hieu va cham luc va ((hanh tai) OR (thanh tai)) cua tre.
