Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir aparente", "heir parent"
"heir apparently" » "huir apparently", "her apparently", "weir apparently", "heir aparentely", "heir parently", "heir apparental", "heir apparent", "heir apparente"
"heir parently" » "huir parently", "her parently", "weir parently", "heir parental", "heir parent", "heir parente"
"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 apparently\"))) OR (\"heir parently\"))) OR (\"wei aparentan\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( heir apparently ))) OR ( heir parently ))) OR ( wei aparentan ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("heir apparently"))) OR ("heir parently"))) OR ("wei aparentan"))*.
