• Performing a fuzzy search may retrieve terms with similar spellings: te sach vu van ((xay hoi) OR (cay phoi)). hieu va ((chat xuc) or (cam xuc)) va dau vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach vu van ((xay hoi) OR (cay phoi)). hieu va ((chat xuc) OR (cam xuc)) va dau vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach vu van ((xay hoi) OR (cay phoi)). hieu va ((chat xuc) or (cam xuc)) va dau vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach vu van ((xay hoi) OR (cay phoi)). hieu va ((chat xuc) or (cam xuc)) va dau vi cua tre*.
