So, the query <a AND b OR c AND d> is parsed to * <(+a +b) (+c +d)> instead of <+a +b +c +d>. * <p> * Check {@link org.apache.lucene.queryparser.flexible.standard.StandardQueryParser} for more details about the * supported syntax and query parser functionalities. */ package org.apache.lucene.queryparser.flexible.precedence;
