• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach thu) OR (sach thue)) nang ma hoa. hieu van cau xuc van ((hanh tai) or (hanh va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach thu) OR (sach thue)) nang ma hoa. hieu van cau xuc van ((hanh tai) OR (hanh va)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach thu) OR (sach thue)) nang ma hoa. hieu van cau xuc van ((hanh tai) or (hanh va)) cua te*".
