• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky ((nang xa) OR (nang x)) hoi. thien van cham tuc va dinh day ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky ((nang xa) OR (nang x)) hoi. thien van cham tuc va dinh day ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky ((nang xa) OR (nang x)) hoi. thien van cham tuc va dinh day ((cua tre) or (cua triet))".
