Examples of org.apache.lucene.search.Query.weight()

org.apache.lucene.search.Query.weight()
Expert: Constructs and initializes a Weight for a top-level query. @deprecated never ever use this method in {@link Weight} implementations.Subclasses of {@code Query} should use {@link #createWeight}, instead.
