• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty lang xa hoi. hieu va lam xuc ca ((dao thi) or (((dan thi) OR (dinh thi)))) du tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang xa hoi. hieu va lam xuc ca ((dao thi) OR (((dan thi) OR (dinh thi)))) du tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang xa hoi. hieu va lam xuc ca ((dao thi) or (((dan thi) OR (dinh thi)))) du tre*".
