Processors used by Precedence Query Parser

<h2>Lucene Precedence Query Parser Processors</h2>

<p>
This package contains the 2 {@link org.apache.lucene.queryparser.flexible.core.processors.QueryNodeProcessor}s used by
{@link org.apache.lucene.queryparser.flexible.precedence.PrecedenceQueryParser}.
</p>
<p>
{@link org.apache.lucene.queryparser.flexible.precedence.processors.BooleanModifiersQueryNodeProcessor}: this processor
is used to apply {@link org.apache.lucene.queryparser.flexible.core.nodes.ModifierQueryNode}s on
{@link org.apache.lucene.queryparser.flexible.core.nodes.BooleanQueryNode} children according to the boolean type
or the default operator.
</p>
<p>
{@link org.apache.lucene.queryparser.flexible.precedence.processors.PrecedenceQueryNodeProcessorPipeline}: this
processor pipeline is used by {@link org.apache.lucene.queryparser.flexible.precedence.PrecedenceQueryParser}. It extends
{@link org.apache.lucene.queryparser.flexible.standard.processors.StandardQueryNodeProcessorPipeline} and rearrange
the pipeline so the boolean precedence is processed correctly. Check {@link org.apache.lucene.queryparser.flexible.precedence.processors.PrecedenceQueryNodeProcessorPipeline}
for more details.
