Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "weir apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir parentales" » "her parentales", "weir parentales", "hair parentales", "heir parental", "heir aparenteales", "heir parentalales"
"heir aaparenteely" » "her aaparenteely", "weir aaparenteely", "hair aaparenteely", "heir apparently", "heir aaaparenteeely", "heir aaparentaleely"
"huir parent" » "huir aparente", "huir 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 parentales") OR ("heir aaparenteely"))))) OR ("huir parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparent\") OR (((\"heir parentales\") OR (\"heir aaparenteely\"))))) OR (\"huir parent\"))*".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ((( heir parentales ) OR ( heir aaparenteely ))))) OR ( huir parent ))*.
