## 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

Specified by:
  `createWeight` in class `SpanQuery`
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:
  `visit` in class `Query`

### equals

public boolean equals(Object other)
Returns true iff `o` is equal to this.

Specified by:
  `equals` in class `Query`

### hashCode

public int hashCode()

Specified by:
  `hashCode` in class `Query`
