```
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.
