Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "herr apparent", "heir aparente", "heir parent"
"heir apparently" » "huir apparently", "her apparently", "herr apparently", "heir aparentely", "heir parently", "heir apparental", "heir apparent", "heir apparente"
"hair parently" » "hair parental", "hair parent", "hair parente"
"weir aparentely" » "weis aparentely", "wei aparentely", "weil aparentely", "weir aparente", "weir aparentes"

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 ((((("heir apparently") OR ("hair parently"))) OR ("weir aparentely"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"heir apparent\") OR (((((\"heir apparently\") OR (\"hair parently\"))) OR (\"weir aparentely\"))))".
• Removing quotes may allow a broader search: (( heir apparent ) OR ((((( heir apparently ) OR ( hair parently ))) OR ( weir aparentely )))).
• Adding a wildcard symbol may retrieve word variants: (("heir apparent") OR ((((("heir apparently") OR ("hair parently"))) OR ("weir aparentely"))))*.
