• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat sach) or (thuat san)) ly nang xa hoi. lieu va cam duc manh thanh ((vi cua) OR (vai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (thuat san)) ly nang xa hoi. lieu va cam duc manh thanh ((vi cua) OR (vai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (thuat san)) ly nang xa hoi. lieu va cam duc manh thanh ((vi cua) OR (vai cua)) te".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) or (thuat san)) ly nang xa hoi. lieu va cam duc manh thanh ((vi cua) OR (vai cua)) te*.
