• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach 2 dan tay hoi. hieu va ((cham loc) or (cham soc)) va hanh vai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach 2 dan tay hoi. hieu va ((cham loc) OR (cham soc)) va hanh vai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach 2 dan tay hoi. hieu va ((cham loc) or (cham soc)) va hanh vai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thuat sach 2 dan tay hoi. hieu va ((cham loc) or (cham soc)) va hanh vai ((cua tre) OR (cuu tre))*.
