Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "weir apparent", "herr apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentely" » "her aparentely", "weir aparentely", "herr aparentely", "heir aparente", "heir apparently", "heir aparentes", "heir aaparenteely", "heir aparentalely"
"hair apaparenteal" » "hair apaaparenteeal", "hair apaparentaleal"
"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 (\"hair apaparenteal\"))) OR (\"heir aparentely\"))) OR (\"huir parent\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( hair apaparenteal ))) OR ( heir aparentely ))) OR ( huir parent ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("hair apaparenteal"))) OR ("heir aparentely"))) OR ("huir parent"))*.
