      public static final class SpanMultiTermQueryWrapper.TopTermsSpanBooleanQueryRewrite
      extends SpanMultiTermQueryWrapper.SpanRewriteMethod

  A rewrite method that first translates each term into a SpanTermQuery in a `BooleanClause.Occur.SHOULD` clause in a BooleanQuery, and keeps the scores as computed by the query.

  This rewrite method only uses the top scoring terms so it will not overflow the boolean max clause count.
