Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentely" » "huir aparentely", "her aparentely", "weir aparentely", "heir aparente", "heir apparently", "heir aaparenteely", "heir aparentalely"
"heir aparentes" » "huir aparentes", "her aparentes", "weir aparentes", "heir aparente", "heir parente", "heir parientes", "heir aaparentees", "heir aparentales"
"heir parent" » "huir parent", "her parent", "weir parent", "heir aparente", "heir parental"

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 aparentely") OR ("heir aparentes"))))) OR ("heir parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparent\") OR (((\"heir aparentely\") OR (\"heir aparentes\"))))) OR (\"heir parent\"))*".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ((( heir aparentely ) OR ( heir aparentes ))))) OR ( heir parent ))*.
