Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "hair apparent", "herr apparent", "heir apparently", "heir aparente", "heir parent"
"huir apparent" » "huir apparently", "huir aparente", "huir parent"
"weir apparental" » "weir apparentlyal", "weir aparenteal", "weir parental", "weis apparental", "wei apparental", "weil apparental", "weir apparently", "weir aparentan"
"weir parently" » "weis parently", "wei parently", "weil parently", "weir apparently", "weir parental", "weir parent"

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 (\"huir apparent\"))) OR (((\"weir apparental\") OR (\"weir parently\"))))~".
• Removing quotes may allow a broader search: (((( heir apparent ) OR ( huir apparent ))) OR ((( weir apparental ) OR ( weir parently ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("heir apparent") OR ("huir apparent"))) OR ((("weir apparental") OR ("weir parently"))))*.
