• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach thu)) xang xa hoi. thien van lam duoc va ((hang tai) or (hang va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach thu)) xang xa hoi. thien van lam duoc va ((hang tai) OR (hang va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach thu)) xang xa hoi. thien van lam duoc va ((hang tai) or (hang va)) cua tre*".
