-/**
- * <p>
- * This class is a helper that enables users to easily use the Lucene query
- * parser.
- * </p>
- * <p>
- * To construct a Query object from a query string, use the
- * {@link #parse(String, String)} method:
- * <ul>
- * StandardQueryParser queryParserHelper = new StandardQueryParser(); <br/>
- * Query query = queryParserHelper.parse("a AND b", "defaultField");
- * </ul>
- * <p>
- * To change any configuration before parsing the query string do, for example:
- * <p/>
- * <ul>
- * // the query config handler returned by {@link StandardQueryParser} is a
- * {@link StandardQueryConfigHandler} <br/>
- * queryParserHelper.getQueryConfigHandler().setAnalyzer(new
- * WhitespaceAnalyzer());
- * </ul>
- * <p>
- * The syntax for query strings is as follows (copied from the old QueryParser
- * javadoc):
- * <ul>
- * A Query is a series of clauses. A clause may be prefixed by:
- * <ul>
- * <li>a plus (<code>+</code>) or a minus (<code>-</code>) sign, indicating that
- * the clause is required or prohibited respectively; or
- * <li>a term followed by a colon, indicating the field to be searched. This
- * enables one to construct queries which search multiple fields.
- * </ul>
- *
- * A clause may be either:
- * <ul>
- * <li>a term, indicating all the documents that contain this term; or
- * <li>a nested query, enclosed in parentheses. Note that this may be used with
- * a <code>+</code>/<code>-</code> prefix to require any of a set of terms.
- * </ul>
- *
- * Thus, in BNF, the query grammar is:
- *
- * <pre>
- * Query ::= ( Clause )*
- * Clause ::= ["+", "-"] [<TERM> ":"] ( <TERM> | "(" Query ")" )
- * </pre>
- *
- * <p>
- * Examples of appropriately formatted queries can be found in the <a
- * href="../../../../../../queryparsersyntax.html">query syntax
- * documentation</a>.
- * </p>
- * </ul>
- * <p>
- * The text parser used by this helper is a {@link StandardSyntaxParser}.
- * <p/>
- * <p>
- * The query node processor used by this helper is a
- * {@link StandardQueryNodeProcessorPipeline}.
- * <p/>
- * <p>
- * The builder used by this helper is a {@link StandardQueryTreeBuilder}.
- * <p/>

- * @see StandardQueryConfigHandler
