This boosts apple 3 times in relation to the other query clauses. If
there are no other query clauses, it's a bit meaningless.

Lucene does some "weighting" of the query that causes this to happen.
class Query { [...]
/** Expert: Constructs and initializes a Weight for a top-level query. */
public Weight weight(Searcher searcher)
throws IOException {
Query query = searcher.rewrite(this);
Weight weight = query.createWeight(searcher);
float sum = weight.sumOfSquaredWeights();
float norm = getSimilarity(searcher).queryNorm(sum);
weight.normalize(norm);
return weight;
}
Are you simply curious about this, or is it causing you a problem somehow?
