• Performing a fuzzy search may retrieve terms with similar spellings: (("hoi phat cau.") OR ((("hoi nhap cau.") OR ((("thoi phap cau.") OR ("thoi phap chu."))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hoi phat cau.\") OR (((\"hoi nhap cau.\") OR (((\"thoi phap cau.\") OR (\"thoi phap chu.\"))))))".
• Removing quotes may allow a broader search: (( hoi phat cau. ) OR ((( hoi nhap cau. ) OR ((( thoi phap cau. ) OR ( thoi phap chu. )))))).
• Adding a wildcard symbol may retrieve word variants: (("hoi phat cau.") OR ((("hoi nhap cau.") OR ((("thoi phap cau.") OR ("thoi phap chu."))))))*.
