I m trying below query with "explain": true on million of articles. but top\_terms, top\_terms\_boost and top\_terms\_blended\_freqs returning me the same result.

```auto
"query": {
    "span_multi": {
      "match": {
        "prefix": {
          "article.title": {
            "value": "intr",
            "rewrite": "top_terms_3"
          }
        }
      }
    }
  }

```

In result I can see same top terms of all the 3 rewrite options.  
weight(spanOr([article.title:intr, article.title:intr001, article.title:intra]) in 184380) [PerFieldSimilarity]

I was trying to see the difference in all 3 rewrite options I have gone through the documentation [rewrite parameter | Elasticsearch Guide [8.10] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-term-rewrite.html)  
but still not clear to me. if you can explain these option bit more and why its not working.
