• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) OR (toc sach)) y nang tai hoi. hieu ve cac tu gia thanh tai ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) y nang tai hoi. hieu ve cac tu gia thanh tai ((cuu tre) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y nang tai hoi. hieu ve cac tu gia thanh tai ((cuu tre) or (cua tre))".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) y nang tai hoi. hieu ve cac tu gia thanh tai ((cuu tre) or (cua tre))*.
