    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `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'/>
