• Performing a fuzzy search may retrieve terms with similar spellings: so ((sang ky) OR (tang ky)) lang xa hoi. hieu van cac ((xuc cac) or (tuc cac)) dan da cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sang ky) OR (tang ky)) lang xa hoi. hieu van cac ((xuc cac) OR (tuc cac)) dan da cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sang ky) OR (tang ky)) lang xa hoi. hieu van cac ((xuc cac) or (tuc cac)) dan da cua cu".
• Adding a wildcard symbol may retrieve word variants: so ((sang ky) OR (tang ky)) lang xa hoi. hieu van cac ((xuc cac) or (tuc cac)) dan da cua cu*.
