• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ty) OR (sach tu)) xang xa hoi. lieu va nay tuc va ((dan va) or (ban va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ty) OR (sach tu)) xang xa hoi. lieu va nay tuc va ((dan va) OR (ban va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ty) OR (sach tu)) xang xa hoi. lieu va nay tuc va ((dan va) or (ban va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: so ((sach ty) OR (sach tu)) xang xa hoi. lieu va nay tuc va ((dan va) or (ban va)) cua tre*.
