org.apache.lucene.queryparser.flexible.standard.StandardQueryParser
query config handler returned by {@link StandardQueryParser} is a{@link StandardQueryConfigHandler}
queryParserHelper.getQueryConfigHandler().setAnalyzer(new WhitespaceAnalyzer());

The syntax for query strings is as follows (copied from the old QueryParser javadoc):

a plus (+) or a minus (-) sign, indicating that the clause is required or prohibited respectively; or
a term followed by a colon, indicating the field to be searched. This enables one to construct queries which search multiple fields.

a term, indicating all the documents that contain this term; or
a nested query, enclosed in parentheses. Note that this may be used with a +/- prefix to require any of a set of terms.

 Query  ::= ( Clause ) Clause ::= ["+", "-"] [<TERM> ":"] ( <TERM> | "(" Query ")" )

Examples of appropriately formatted queries can be found in the query syntax documentation.

The text parser used by this helper is a {@link StandardSyntaxParser}.

The query node processor used by this helper is a {@link StandardQueryNodeProcessorPipeline}.

The builder used by this helper is a {@link StandardQueryTreeBuilder}.
