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.
