• Performing a fuzzy search may retrieve terms with similar spellings: (("thep xanh lam tanh f.c.") or ((("thep dinh may tinh hoc.") OR ("thep trinh may tinh hoc."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("thep xanh lam tanh f.c.") OR ((("thep dinh may tinh hoc.") OR ("thep trinh may tinh hoc."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"thep xanh lam tanh f.c.\") or (((\"thep dinh may tinh hoc.\") OR (\"thep trinh may tinh hoc.\"))))*".
• Removing quotes may allow a broader search: (( thep xanh lam tanh f.c. ) or ((( thep dinh may tinh hoc. ) OR ( thep trinh may tinh hoc. ))))*.
