• Performing a fuzzy search may retrieve terms with similar spellings: (((("tang truong thanh de") OR ("tang truong hanh de"))) or ((("tang truong kinh te") or ("tang truong giang te"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tang truong thanh de") OR ("tang truong hanh de"))) OR ((("tang truong kinh te") OR ("tang truong giang te")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tang truong thanh de\") OR (\"tang truong hanh de\"))) or (((\"tang truong kinh te\") or (\"tang truong giang te\"))))".
• Removing quotes may allow a broader search: (((( tang truong thanh de ) OR ( tang truong hanh de ))) or ((( tang truong kinh te ) or ( tang truong giang te )))).
• Adding a wildcard symbol may retrieve word variants: (((("tang truong thanh de") OR ("tang truong hanh de"))) or ((("tang truong kinh te") or ("tang truong giang te"))))*.
