Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"weir apparent" » "weir apparently", "weir aparente", "wei apparent", "weil apparent", "weir apaparente", "weir apparental"
"weis apparent" » "weis apparently", "weis aparente", "weis apaparente", "weis 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 ((("weir apparent") OR ((("weis apparent") OR ("weis parent"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"heir apparent\") OR (((\"weir apparent\") OR (((\"weis apparent\") OR (\"weis parent\"))))))".
• Removing quotes may allow a broader search: (( heir apparent ) OR ((( weir apparent ) OR ((( weis apparent ) OR ( weis parent )))))).
• Adding a wildcard symbol may retrieve word variants: (("heir apparent") OR ((("weir apparent") OR ((("weis apparent") OR ("weis parent"))))))*.
