There is no way around using a separate Scorer for this. You can make (could have made) the scorer by starting from DisjunctionSumScorer.java here: http://svn.apache.org/viewcvs.cgi/lucene/java/trunk/src/java/org/apache/lucene/search/ and rewrite it into a DisjunctionMaxScorer. You can extend QueryParser by subclassing it and override getBooleanQuery() to use your query when the first clause equals for example '_max' and all other clauses are optional.
