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