Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir apparently", "heir aparente", "heir parent"
"weir apparent" » "weir apparently", "weir aparente", "weir parent", "weis apparent", "wei apparent"
"weil apparent" » "weil apparently", "weil aparente", "weil parent"
"weil aparentely" » "weil aparente", "weil apparently", "weil aparentes"

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 ("weir apparent"))) OR ((("weil apparent") OR ("weil aparentely"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparent\") OR (\"weir apparent\"))) OR (((\"weil apparent\") OR (\"weil aparentely\"))))*".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ( weir apparent ))) OR ((( weil apparent ) OR ( weil aparentely ))))*.
