30 * This pipeline has all the processors needed to process a query node tree,
31 * generated by {@link StandardSyntaxParser}, already assembled. <br/>
33 * The order they are assembled affects the results. <br/>
35 * This processor pipeline was designed to work with
36 * {@link StandardQueryConfigHandler}. <br/>
38 * The result query node tree can be used to build a {@link Query} object using
39 * {@link StandardQueryTreeBuilder}. <br/>
