• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty xang xa hoi. hieu ((va nham) or (va tham)) thuc dan doanh ((thu cua) OR (hu cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty xang xa hoi. hieu ((va nham) OR (va tham)) thuc dan doanh ((thu cua) OR (hu cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty xang xa hoi. hieu ((va nham) or (va tham)) thuc dan doanh ((thu cua) OR (hu cua)) te*".
