Perhaps you should try some spelling variations:
"heir apaparente" » "huir apaparente", "her apaparente", "weir apaparente", "heir aparente", "heir apaaparentee", "heir apaparentale"
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aaparentealalely" » "huir aaparentealalely", "her aaparentealalely", "weir aaparentealalely", "heir aaaparenteealalely", "heir aaparentalealalely"
"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.

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