• Performing a fuzzy search may retrieve terms with similar spellings: (((("te cac doanh tren") or ("de cac doanh tri"))) or ((("ve cac dan tri") OR ("ve cac dan thi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("te cac doanh tren") OR ("de cac doanh tri"))) OR ((("ve cac dan tri") OR ("ve cac dan thi")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"te cac doanh tren\") or (\"de cac doanh tri\"))) or (((\"ve cac dan tri\") OR (\"ve cac dan thi\"))))".
• Removing quotes may allow a broader search: (((( te cac doanh tren ) or ( de cac doanh tri ))) or ((( ve cac dan tri ) OR ( ve cac dan thi )))).
• Adding a wildcard symbol may retrieve word variants: (((("te cac doanh tren") or ("de cac doanh tri"))) or ((("ve cac dan tri") OR ("ve cac dan thi"))))*.
