Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "weir apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aaparentealely" » "her aaparentealely", "weir aaparentealely", "hair aaparentealely", "heir aaaparenteealely", "heir aaparentalealely"
"heir parent" » "her parent", "weir parent", "hair parent", "heir aparente", "heir parental"
"huir aparentalely" » "huir parentales", "huir aaparentealely", "huir aparentalalely"

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 (((\"huir aparentalely\") OR (\"heir aaparentealely\"))))) OR (\"heir parent\"))~".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ((( huir aparentalely ) OR ( heir aaparentealely ))))) OR ( heir parent ))~.
• Adding a wildcard symbol may retrieve word variants: (((("heir apparent") OR ((("huir aparentalely") OR ("heir aaparentealely"))))) OR ("heir parent"))*.
