Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "weir apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir apaparente" » "her apaparente", "weir apaparente", "hair apaparente", "heir aparente", "heir apaaparentee", "heir apaparentale"
"huir apparent" » "huir apparently", "huir aparente", "huir apaparente", "huir apparental"
"weis parent" » "weis aparente", "weis parental"

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 apaparente"))) OR ("huir apparent"))) OR ("weis parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"heir apparent\") OR (\"heir apaparente\"))) OR (\"huir apparent\"))) OR (\"weis parent\"))".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( heir apaparente ))) OR ( huir apparent ))) OR ( weis parent )).
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("heir apaparente"))) OR ("huir apparent"))) OR ("weis parent"))*.
