• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach y)) xang va hoi. hieu va cham xuc va thanh vi ((cua triet) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) xang va hoi. hieu va cham xuc va thanh vi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) xang va hoi. hieu va cham xuc va thanh vi ((cua triet) or (va triet))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach y)) xang va hoi. hieu va cham xuc va thanh vi ((cua triet) or (va triet))*.
