• Performing a fuzzy search may retrieve terms with similar spellings: co sach thu trong cac hoc. hieu qua ((cham xuc) or (cham soc)) va hanh vai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: co sach thu trong cac hoc. hieu qua ((cham xuc) OR (cham soc)) va hanh vai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach thu trong cac hoc. hieu qua ((cham xuc) or (cham soc)) va hanh vai ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: co sach thu trong cac hoc. hieu qua ((cham xuc) or (cham soc)) va hanh vai ((cua te) OR (cua tu))*.
