• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky ((dang ma) or (dang mau)) hoi. hieu ((ve cam) OR (va cam)) xuc va danh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky ((dang ma) OR (dang mau)) hoi. hieu ((ve cam) OR (va cam)) xuc va danh va cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky ((dang ma) or (dang mau)) hoi. hieu ((ve cam) OR (va cam)) xuc va danh va cuu tre*".
