    public class AnyQueryNode
    extends AndQueryNode

A `AnyQueryNode` represents an ANY operator performed on a list of nodes.

Constructor and Description
`AnyQueryNode(List<QueryNode> clauses, CharSequence field, int minimumMatchingElements)`

### Method Summary

Methods
`QueryNode` `cloneTree()` Recursive clone the QueryNode tree The tags are not copied to the new tree when you call the cloneTree() method
`CharSequence` `getField()` returns null if the field was not specified
`String` `getFieldAsString()` returns - null if the field was not specified
`int` `getMinimumMatchingElements()`
`void` `setField(CharSequence field)`
`CharSequence` `toQueryString(EscapeQuerySyntax escapeSyntaxParser)` convert to a query string understood by the query parser
`String` `toString()` Every implementation of this class should return pseudo xml like this: For FieldQueryNode: <field start='1' end='2' field='subject' text='foo'/>
