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