- ## Constructor Details

  - ### SpanNotQuery

    public SpanNotQuery(SpanQuery include, SpanQuery exclude)
    Construct a SpanNotQuery matching spans from `include` which have no overlap with spans from `exclude`.

  - ### SpanNotQuery

    public SpanNotQuery(SpanQuery include, SpanQuery exclude, int dist)
    Construct a SpanNotQuery matching spans from `include` which have no overlap with spans from `exclude` within `dist` tokens of `include`. Inversely, a negative `dist` value may be used to specify a certain amount of allowable overlap.

  - ### SpanNotQuery

    public SpanNotQuery(SpanQuery include, SpanQuery exclude, int pre, int post)
    Construct a SpanNotQuery matching spans from `include` which have no overlap with spans from `exclude` within `pre` tokens before or `post` tokens of `include`. Inversely, negative values for `pre` and/or `post` allow a certain amount of overlap to occur.

- ## Method Details

  - ### getInclude

    public SpanQuery getInclude()
    Return the SpanQuery whose matches are filtered.

  - ### getExclude

    public SpanQuery getExclude()
    Return the SpanQuery whose matches must not overlap those returned.

  - ### getField

    public String getField()
    Description copied from class: `SpanQuery`
    Returns the name of the field matched by this query.
    Specified by:
      `getField` in class `SpanQuery`

  - ### toString

    public String toString(String field)
    Specified by:
      `toString` in class `Query`

  - ### createWeight

    public SpanWeight createWeight(IndexSearcher searcher, ScoreMode scoreMode, float boost) throws IOException

  - ### rewrite

    public Query rewrite(IndexSearcher indexSearcher) throws IOException
    Overrides:
      `rewrite` in class `Query`
    Throws:
      `IOException`

  - ### visit

    public void visit(QueryVisitor visitor)
    Specified by:
