• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang xa hoi. hieu vu cham ((xuc va) or (tuc va)) han ((dau cuu) OR (dau cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. hieu vu cham ((xuc va) OR (tuc va)) han ((dau cuu) OR (dau cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. hieu vu cham ((xuc va) or (tuc va)) han ((dau cuu) OR (dau cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. hieu vu cham ((xuc va) or (tuc va)) han ((dau cuu) OR (dau cua)) tre*.
