• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu ((bang xa) OR (mang xa)) hoi. hieu van hao duc va danh ((va chua) or (ca cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((bang xa) OR (mang xa)) hoi. hieu van hao duc va danh ((va chua) OR (ca cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((bang xa) OR (mang xa)) hoi. hieu van hao duc va danh ((va chua) or (ca cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach thu ((bang xa) OR (mang xa)) hoi. hieu van hao duc va danh ((va chua) or (ca cua)) te*.
