Perhaps you should try some spelling variations:
"heir apaparente" » "huir apaparente", "her apaparente", "hair apaparente", "heir aparente", "heir apaaparentee", "heir apaparentale"
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir parent" » "huir parent", "her parent", "hair parent", "heir aparente", "heir parental"
"weir apaparente" » "weir aparente", "weis apaparente", "wei apaparente", "weil apaparente", "weir apaaparentee", "weir apaparentale"

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

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