• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach thu) OR (sach tham)) huong x ho. hieu ve cau ((duoc van) or (duoc va)) hanh lam chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach tham)) huong x ho. hieu ve cau ((duoc van) OR (duoc va)) hanh lam chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) OR (sach tham)) huong x ho. hieu ve cau ((duoc van) or (duoc va)) hanh lam chau tre".
