• Performing a fuzzy search may retrieve terms with similar spellings: (("pho gian dang tien thu") or ((("pho cap qua tiep can") or ((((((("pham san lan dieu tra") OR ("pham van lan dieu tra"))) or ("pham san dang dieu cua"))) or ("pho sach danh dieu tri"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pho gian dang tien thu") OR ((("pho cap qua tiep can") OR ((((((("pham san lan dieu tra") OR ("pham van lan dieu tra"))) OR ("pham san dang dieu cua"))) OR ("pho sach danh dieu tri"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pho gian dang tien thu\") or (((\"pho cap qua tiep can\") or (((((((\"pham san lan dieu tra\") OR (\"pham van lan dieu tra\"))) or (\"pham san dang dieu cua\"))) or (\"pho sach danh dieu tri\"))))))*".
• Removing quotes may allow a broader search: (( pho gian dang tien thu ) or ((( pho cap qua tiep can ) or ((((((( pham san lan dieu tra ) OR ( pham van lan dieu tra ))) or ( pham san dang dieu cua ))) or ( pho sach danh dieu tri ))))))*.
