• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach tu) OR (sach ty)) hang ca hoi. ((hieu va) or (lieu va)) cam luc gia thanh ve cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach ty)) hang ca hoi. ((hieu va) OR (lieu va)) cam luc gia thanh ve cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach ty)) hang ca hoi. ((hieu va) or (lieu va)) cam luc gia thanh ve cuu tre*".
