- ## Method Details

  - ### matches

    public Matches matches(LeafReaderContext context, int doc) throws IOException
    Description copied from class: `Weight`
    Returns `Matches` for a specific document, or `null` if the document does not match the parent query

    A query match that contains no position information (for example, a Point or DocValues query) will return `MatchesUtils.MATCH_WITH_NO_TERMS`

    Overrides:
      `matches` in class `Weight`
    Parameters:
      `context` - the reader's context to create the `Matches` for
      `doc` - the document's id relative to the given context's reader
    Throws:
      `IOException`

  - ### scorerSupplier

    public ScorerSupplier scorerSupplier(LeafReaderContext context) throws IOException
    Description copied from class: `Weight`
    Get a `ScorerSupplier`, which allows knowing the cost of the `Scorer` before building it. A scorer supplier for the same `LeafReaderContext` instance may be requested multiple times as part of a single search call.

    Note: It must return null if the scorer is null.

    Specified by:
      `scorerSupplier` in class `Weight`
    Parameters:
      `context` - the leaf reader context
    Returns:
      a `ScorerSupplier` providing the scorer, or null if scorer is null
    Throws:
      `IOException` - if an IOException occurs
    See Also:
      - `Scorer`
      - `Weight.DefaultScorerSupplier`

  - ### isCacheable

    public boolean isCacheable(LeafReaderContext ctx)
    Returns:
      `true` if the object can be cached against a given leaf

  - ### explain

    public Explanation explain(LeafReaderContext context, int doc) throws IOException
    Description copied from class: `Weight`
    An explanation of the score computation for the named document.
    Specified by:
      `explain` in class `Weight`
    Parameters:
      `context` - the readers context to create the `Explanation` for.
      `doc` - the document's id relative to the given context's reader
    Returns:
      an Explanation for the score
    Throws:
      `IOException` - if an `IOException` occurs
