Hi,  
I am using _ES 7.7_ and indexed around _70K_ data. I also verified index has around _540 fields_ by invoking`http://es_host:port/2/_mapping`.

While performing simple search query I am getting `query_shard_exception`.

```auto
    GET http://es_host:port/2/_search?q=*
    Response:
    {
      "root_cause" : [
      {
    	"type" : "query_shard_exception",
    	"reason" : "failed to create query: field expansion matches too many fields, limit: 1024, got: 1139"
      }
    }

```

Same error I am facing for query having bool must clause which has only 3 terms.  
I was using `ES 5.5.3` earlier and did not face this issue and only getting after migrated to `ES 7.7`

Queries:

1. Why am I getting this error ? How to resolve above issue ?
2. If solution is to specify `indices.query.bool.max_clause_count` then what should be the max allowed value? [my fields are dynamic and I can create N number of fields]
3. If my index has around **540 fields** , then why **1139 fields** has been mentioned in es error ?
4. Is there any solution apart from #2 ?
