• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((((sang tai) OR (sang than))) or (hang tai)) hai. hieu ve cam luc va kinh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((((sang tai) OR (sang than))) OR (hang tai)) hai. hieu ve cam luc va kinh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((((sang tai) OR (sang than))) or (hang tai)) hai. hieu ve cam luc va kinh vi cua te*".
