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