Examples of org.apache.lucene.index.DocsEnum.freq()

org.apache.lucene.index.DocsEnum.freq()
Returns term frequency in the current document, or 1 if the field was indexed with {@link IndexOptions#DOCS_ONLY}. Do not call this before {@link #nextDoc} is first called, nor after {@link #nextDoc} returns{@link DocIdSetIterator#NO_MORE_DOCS}.
NOTE: if the {@link DocsEnum} was obtain with {@link #FLAG_NONE}, the result of this method is undefined.
