Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "heir aparente", "heir apparente", "heir apparents", "heir apaparente"
"heir apparently" » "her apparently", "heir aparentely", "heir apparentely", "heir apparentsly", "heir apaparentely"
"heir aparentalalalely" » "her aparentalalalely", "heir aparentealalalely", "heir aparentsalalalely", "heir aaparentealalalely"
"huir parent" » "huir parente", "huir parents", "huir aparente"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("heir apparent") OR ("heir apparently"))) OR ("heir aparentalalalely"))) OR ("huir parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"heir apparent\") OR (\"heir apparently\"))) OR (\"heir aparentalalalely\"))) OR (\"huir parent\"))*".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( heir apparently ))) OR ( heir aparentalalalely ))) OR ( huir parent ))*.
