• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ly vang xa hoi. hieu ((va cam) or (va cao)) xuc va thanh van ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly vang xa hoi. hieu ((va cam) OR (va cao)) xuc va thanh van ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly vang xa hoi. hieu ((va cam) or (va cao)) xuc va thanh van ((cua tre) OR (cua te))".
