- Constructor Detail
  - SpanNotQuery
```
public SpanNotQuery(SpanQuery include,
                    SpanQuery exclude)
```
    Construct a SpanNotQuery matching spans from include which have no overlap with spans from exclude.
- Method Detail
  - 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
  - extractTerms
```
public void extractTerms(Set<Term> terms)
```
    Description copied from class: Query
    
    Expert: adds all terms occurring in this query to the terms set. Only works if this query is in its rewritten form.
    
    Overrides:
    
    extractTerms in class Query
  - 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.
    The representation used is one that is supposed to be readable by QueryParser. However, there are the following limitations:
    
    If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
    
    Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.
    Specified by:
    
    toString in class Query
  - clone
```
public Object clone()
```
    Description copied from class: Query
    
    Returns a clone of this query.
    
    Overrides:
    
    clone in class Query
  - getSpans
```
public Spans getSpans(IndexReader reader)
               throws IOException
```
    Description copied from class: SpanQuery
    
    Expert: Returns the matches for this query in an index. Used internally to search for spans.
    
    Specified by:
    
    getSpans in class SpanQuery
    
    Throws:
    
    IOException
  - 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
  - equals
```
public boolean equals(Object o)
```
    Returns true iff o is equal to this.
    
    Overrides:
    
    equals in class Query
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Query
