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