- - ### Constructor Detail

    - #### SpanContainingQuery

          public SpanContainingQuery(SpanQuery big,
                                     SpanQuery little)

      Construct a SpanContainingQuery matching spans from `big` that contain at least one spans from `little`. This query has the boost of `big`. `big` and `little` must be in the same field.

  - ### Method Detail

    - #### toString

          public String toString(String field)

      Description copied from class: `Query`
      Prints a query to a string, with `field` assumed to be the default field and omitted.
      Specified by:
        `toString` in class `Query`

    - #### createWeight

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

      Description copied from class: `Query`
      Expert: Constructs an appropriate Weight implementation for this query.

      Only implemented by primitive queries, which re-write to themselves.

      Specified by:
        `createWeight` in class `SpanQuery`
        `scoreMode` - How the produced scorers will be consumed.
        `boost` - The boost that is propagated by the parent queries.
      Throws:
        `IOException`

    - #### 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`

    - #### getBig

          public SpanQuery getBig()

    - #### getLittle

          public SpanQuery getLittle()

    - #### rewrite

          public Query rewrite(IndexReader reader)
                        throws IOException

      Description copied from class: `Query`
      Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.
      Overrides:
        `rewrite` in class `Query`
      Throws:
        `IOException`

    - #### visit

          public void visit(QueryVisitor visitor)

      Description copied from class: `Query`
      Recurse through the query tree, visiting any child queries
      Overrides:
        `visit` in class `Query`
      Parameters:
        `visitor` - a QueryVisitor to be called by each query in the tree

    - #### equals

          public boolean equals(Object other)

      Description copied from class: `Query`
      Override and implement query instance equivalence properly in a subclass. This is required so that `QueryCache` works properly. Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical that other instance. Utility methods are provided for certain repetitive code.
      Specified by:
        `equals` in class `Query`
      See Also:
        `Query.sameClassAs(Object)`, `Query.classHash()`

    - #### hashCode

          public int hashCode()

      Description copied from class: `Query`
      Override and implement query hash code properly in a subclass. This is required so that `QueryCache` works properly.
      Specified by:
        `hashCode` in class `Query`
      See Also:
        `Query.equals(Object)`
