• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty hang x hoi. hieu ha nam sua ((va hanh) OR (va danh)) ((vinh cuu) or (manh cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty hang x hoi. hieu ha nam sua ((va hanh) OR (va danh)) ((vinh cuu) OR (manh cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty hang x hoi. hieu ha nam sua ((va hanh) OR (va danh)) ((vinh cuu) or (manh cua)) tre".
