Examples of StandardQueryParser

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

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}.
