/** 
 * Precedence Query Parser Implementation
 * 
 * 
Lucene Precedence Query Parser
 * 
 * 

 * The Precedence Query Parser extends the Standard Query Parser and enables 
 * the boolean precedence. So, the query <a AND b OR c AND d> is parsed to 
 * <(+a +b) (+c +d)> instead of <+a +b +c +d>.
 * 

 * Check {@link org.apache.lucene.queryparser.flexible.standard.StandardQueryParser} for more details about the
 * supported syntax and query parser functionalities.
