Perhaps you should try some spelling variations:
"heir apparent" » "her apparent", "herr apparent", "meir apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"weir apparent" » "weir apparently", "weir aparente", "weis apparent", "wei apparent", "weil apparent", "weir apaparente", "weir apparental"
"huir aparentalalely" » "huir aaparentealalely", "huir aparentalalalely"
"hair parent" » "hair aparente", "hair parental"

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