• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (toc sach)) ty hang xa hoi. hieu va cham xuc va hanh hai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ty hang xa hoi. hieu va cham xuc va hanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ty hang xa hoi. hieu va cham xuc va hanh hai ((cua tre) OR (cua triet))".
