• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((sang ma) or (mang may)) hoi. hieu va cam luc va xanh ((di cua) OR (doi cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((sang ma) OR (mang may)) hoi. hieu va cam luc va xanh ((di cua) OR (doi cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((sang ma) or (mang may)) hoi. hieu va cam luc va xanh ((di cua) OR (doi cua)) te*".
