Examples of org.apache.lucene.document.Fieldable

org.apache.lucene.document.Fieldable
Synonymous with {@link Field}.
WARNING: This interface may change within minor versions, despite Lucene's backward compatibility requirements. This means new methods may be added from version to version. This change only affects the Fieldable API; other backwards compatibility promises remain intact. For example, Lucene can still read and write indices created within the same major version.
