• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky trang xa hoi. hieu ((va cam) or (vien da)) tuc va hanh ((vi cua) OR (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky trang xa hoi. hieu ((va cam) OR (vien da)) tuc va hanh ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky trang xa hoi. hieu ((va cam) or (vien da)) tuc va hanh ((vi cua) OR (di cua)) tre*".
