• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. hieu vu cham ((xuc va) or (tuc va)) ((dinh lai) OR (dinh lam)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. hieu vu cham ((xuc va) OR (tuc va)) ((dinh lai) OR (dinh lam)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. hieu vu cham ((xuc va) or (tuc va)) ((dinh lai) OR (dinh lam)) cua tre*".
