 * <h2>Query Configuration Interfaces</h2>
 * <p>
 * The package <tt>org.apache.lucene.queryparser.flexible.config</tt> contains query configuration handler
 * abstract class that all config handlers should extend.
 * <p>
 * See {@link org.apache.lucene.queryparser.flexible.standard.config.StandardQueryConfigHandler} for a reference
 * implementation.
 * <p>
 * The {@link org.apache.lucene.queryparser.flexible.core.config.QueryConfigHandler} and {@link org.apache.lucene.queryparser.flexible.core.config.FieldConfig} are used in the processors to access config
 * information in a flexible and independent way.
 * See {@link org.apache.lucene.queryparser.flexible.standard.processors.TermRangeQueryNodeProcessor} for a 
 * reference implementation.
