• Performing a fuzzy search may retrieve terms with similar spellings: ((nuoc sach) OR (hoc sach)) tham bang xa hoi. lieu va pham cuu ban ((hang vi) or (hanh vi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nuoc sach) OR (hoc sach)) tham bang xa hoi. lieu va pham cuu ban ((hang vi) OR (hanh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nuoc sach) OR (hoc sach)) tham bang xa hoi. lieu va pham cuu ban ((hang vi) or (hanh vi)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((nuoc sach) OR (hoc sach)) tham bang xa hoi. lieu va pham cuu ban ((hang vi) or (hanh vi)) cuu tre*.
