• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) or (te san)) ky nang ha hoi. hieu va cam xuc ban hang ((vi cua) OR (vai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te san)) ky nang ha hoi. hieu va cam xuc ban hang ((vi cua) OR (vai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te san)) ky nang ha hoi. hieu va cam xuc ban hang ((vi cua) OR (vai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te san)) ky nang ha hoi. hieu va cam xuc ban hang ((vi cua) OR (vai cua)) tre*.
