• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu lang ((van hoi) OR (van hoe)). hieu van ((cau luoc) or (hau loc)) gia hanh vi cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu lang ((van hoi) OR (van hoe)). hieu van ((cau luoc) OR (hau loc)) gia hanh vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu lang ((van hoi) OR (van hoe)). hieu van ((cau luoc) or (hau loc)) gia hanh vi cau treo".
