• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((cong ha) OR (dong ha)) noi. hieu ve cham xuc van thanh ((te cua) or (tue cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((cong ha) OR (dong ha)) noi. hieu ve cham xuc van thanh ((te cua) OR (tue cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((cong ha) OR (dong ha)) noi. hieu ve cham xuc van thanh ((te cua) or (tue cua)) tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ky ((cong ha) OR (dong ha)) noi. hieu ve cham xuc van thanh ((te cua) or (tue cua)) tre*.
