Ampersands [&] Company names Zing locates terms containing punctuation characters that are common in company names: ampersands (&), plus signs (+), or hyphens (-). For example, a search for H&R Block locates exact matches to the search term.
Apostrophes ['] Proper names Zing ignores trailing possessives and retains most others to find company names. For example, a search for O'Reilly's locates matches to O'Reilly and O'Reilly's.
