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