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