• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty dang cau hoi. hieu ((va cam) OR (va cac)) ((xuc va) or (tuc va)) hanh tai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty dang cau hoi. hieu ((va cam) OR (va cac)) ((xuc va) OR (tuc va)) hanh tai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty dang cau hoi. hieu ((va cam) OR (va cac)) ((xuc va) or (tuc va)) hanh tai cua viet".
