• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((sang mai) or (sang tai)) hoi. hieu ve cam ((xuc va) OR (tuc va)) danh tai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang mai) OR (sang tai)) hoi. hieu ve cam ((xuc va) OR (tuc va)) danh tai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang mai) or (sang tai)) hoi. hieu ve cam ((xuc va) OR (tuc va)) danh tai cau tren".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((sang mai) or (sang tai)) hoi. hieu ve cam ((xuc va) OR (tuc va)) danh tai cau tren*.
