I have been following this tutorial to create minhash signature.

> **[MinHash token filter | Elasticsearch Guide \[7.16\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-minhash-tokenfilter.html)**

However, it is unclear to me how to perform searching using minhash properly. I have attempted the following query, which I quickly learned that it is very slow.

```auto
query = {
        "match": {
          "content.hash": {
            "query": "some text...."
          }
        }
      }

```

Any suggestions are greatly appreciated. Thank you!
