• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach thu) or (sach thue)) hang xa hoi. lieu va cham duc va tinh hai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach thu) OR (sach thue)) hang xa hoi. lieu va cham duc va tinh hai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach thu) or (sach thue)) hang xa hoi. lieu va cham duc va tinh hai ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach thu) or (sach thue)) hang xa hoi. lieu va cham duc va tinh hai ((cua tre) OR (cuu tre))*.
