• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty xang ma hoi. hieu van cau phuc van ((((nhan tai) OR (toan tai))) or (hanh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang ma hoi. hieu van cau phuc van ((((nhan tai) OR (toan tai))) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang ma hoi. hieu van cau phuc van ((((nhan tai) OR (toan tai))) or (hanh vi)) cua te".
