• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) nang x hoi. hieu van ((chat xuc) or (chao xu)) va thanh dam cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) nang x hoi. hieu van ((chat xuc) OR (chao xu)) va thanh dam cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) nang x hoi. hieu van ((chat xuc) or (chao xu)) va thanh dam cua tre*".
