Perhaps you should try some spelling variations:
"heir apparent" » "weir apparent", "hair apparent", "herr apparent", "heir apparently", "heir parent"
"heir aaparenteely" » "weir aaparenteely", "hair aaparenteely", "herr aaparenteely", "heir apparently", "heir aapareceely"
"her apparental" » "her apparentlyal", "her parental", "her apparently", "her aparentan"
"huir aparente" » "huir aparece"

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 (\"her apparental\"))) OR (\"heir aaparenteely\"))) OR (\"huir aparente\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( her apparental ))) OR ( heir aaparenteely ))) OR ( huir aparente ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("her apparental"))) OR ("heir aaparenteely"))) OR ("huir aparente"))*.
