```
public SpanOrQuery(SpanQuery[] clauses)
```
    Construct a SpanOrQuery merging the provided clauses.
- Method Detail
  - getClauses
```
public SpanQuery[] getClauses()
```
    Return the clauses whose spans are matched.
  - getField
```
public java.lang.String getField()
```
    Description copied from class: SpanQuery
    
    Returns the name of the field matched by this query.
    
    Specified by:
    
    getField in class SpanQuery
  - getTerms
```
public java.util.Collection getTerms()
```
    Deprecated. use extractTerms instead
    
    Returns a collection of all terms matched by this query.
    
    Specified by:
    
    getTerms in class SpanQuery

    extractTerms(Set)
  - extractTerms
```
public void extractTerms(java.util.Set 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
  - clone
```
public java.lang.Object clone()
```
    Description copied from class: Query
    
    Returns a clone of this query.
    
    Overrides:
    
    clone in class Query
  - rewrite
```
public Query rewrite(IndexReader reader)
              throws java.io.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:
    
    java.io.IOException
  - toString
```
public java.lang.String toString(java.lang.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
  - equals
```
public boolean equals(java.lang.Object o)
```
    Overrides:
    
    equals in class Query
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Query
  - getSpans
```
public Spans getSpans(IndexReader reader)
               throws java.io.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:
    
    java.io.IOException
