Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "heir apparently", "heir aparente", "heir apparente", "heir apparents", "heir apaparente"
"heir aparentales" » "her aparentales", "heir parentales", "heir aparenteales", "heir aparentsales", "heir aaparenteales", "heir aparentees"
"huir parent" » "huir parente", "huir parents", "huir aparente"
"huir parental" » "huir parenteal", "huir parentsal", "huir aparenteal", "huir parente"

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

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