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

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 ("heir apparently"))) OR ("heir parently"))) OR ("weir aparente"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"heir apparent\") OR (\"heir apparently\"))) OR (\"heir parently\"))) OR (\"weir aparente\"))".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( heir apparently ))) OR ( heir parently ))) OR ( weir aparente )).
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("heir apparently"))) OR ("heir parently"))) OR ("weir aparente"))*.
