Perhaps you should try some spelling variations:
"heir apparent" » "weir apparent", "hair apparent", "herr apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir apparental" » "weir apparental", "hair apparental", "herr apparental", "heir apparentlyal", "heir aparenteal", "heir parental", "heir apparently", "heir aparentan", "heir apaparenteal", "heir apparentalal"
"her aparentalely" » "her parentales", "her aaparentealely", "her aparentalalely"
"huir parent" » "huir aparente", "huir 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 apparent\") OR (\"heir apparental\"))) OR (\"her aparentalely\"))) OR (\"huir parent\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( heir apparental ))) OR ( her aparentalely ))) OR ( huir parent ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("heir apparental"))) OR ("her aparentalely"))) OR ("huir parent"))*.
