• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach kem) or (sach ty)) lang dai hoi. hieu ((ve cham) OR (va cham)) xuc va danh van cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach kem) OR (sach ty)) lang dai hoi. hieu ((ve cham) OR (va cham)) xuc va danh van cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach kem) or (sach ty)) lang dai hoi. hieu ((ve cham) OR (va cham)) xuc va danh van cua tu*".
