Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir aparente"
"heir parently" » "huir parently", "her parently", "weir parently", "heir parental", "heir parente", "heir parents"
"heir parent" » "huir parent", "her parent", "weir parent"
"wei apparently" » "wei aparentely", "wei apparental", "wei apparente", "wei apparents"

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