• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang x hoi. lieu va nam duc va thanh ((((dan cua) OR (dai cua))) or (vang cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. lieu va nam duc va thanh ((((dan cua) OR (dai cua))) OR (vang cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. lieu va nam duc va thanh ((((dan cua) OR (dai cua))) or (vang cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang x hoi. lieu va nam duc va thanh ((((dan cua) OR (dai cua))) or (vang cua)) te*.
