• Performing a fuzzy search may retrieve terms with similar spellings: hoc hieu manh - ((doanh doanh) or (doanh hoan)) ((chua bang) OR (chua xang)) suong anh tuan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - ((doanh doanh) OR (doanh hoan)) ((chua bang) OR (chua xang)) suong anh tuan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - ((doanh doanh) or (doanh hoan)) ((chua bang) OR (chua xang)) suong anh tuan ban*".
