• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach va) OR (sach ha)) dang xa hoi. hieu van ((chat xuc) or (chao xu)) va dao ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach va) OR (sach ha)) dang xa hoi. hieu van ((chat xuc) OR (chao xu)) va dao ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach va) OR (sach ha)) dang xa hoi. hieu van ((chat xuc) or (chao xu)) va dao ca cua tre".
• Adding a wildcard symbol may retrieve word variants: toc ((sach va) OR (sach ha)) dang xa hoi. hieu van ((chat xuc) or (chao xu)) va dao ca cua tre*.
