• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y anh ((tao hoi) OR (tao boi)). hieu ve pham ((duc ban) or (duc tan)) banh thai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y anh ((tao hoi) OR (tao boi)). hieu ve pham ((duc ban) OR (duc tan)) banh thai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y anh ((tao hoi) OR (tao boi)). hieu ve pham ((duc ban) or (duc tan)) banh thai cuu tre*".
