Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "weir apparent", "hair apparent", "heir aparente", "heir parent"
"heir apparently" » "huir apparently", "weir apparently", "hair apparently", "heir aparentely", "heir parently"
"wei apparent" » "wei aparente", "wei parent"
"her apparently" » "her aparentely", "her parently"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("heir apparent") OR ("wei apparent"))) OR ((("heir apparently") OR ("her apparently"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparent\") OR (\"wei apparent\"))) OR (((\"heir apparently\") OR (\"her apparently\"))))".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ( wei apparent ))) OR ((( heir apparently ) OR ( her apparently )))).
• Adding a wildcard symbol may retrieve word variants: (((("heir apparent") OR ("wei apparent"))) OR ((("heir apparently") OR ("her apparently"))))*.
