Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir apparently", "heir aparente", "heir parent"
"heir apparente" » "huir apparente", "her apparente", "weir apparente", "heir apparentlye", "heir aparentee", "heir parente", "heir aparente", "heir apparently"
"heir parently" » "huir parently", "her parently", "weir parently", "heir apparently", "heir parental", "heir parent"
"wei aparentan" » "wei aparentando", "wei aparentaba", "wei emparentan"

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