What we are trying to do is to index a bunch of documents in batches i.e.

```
    foreach (var batch in props.ChunkBy(100))
    {    
    
        var result = await client.IndexManyAsync<Type>(batch, indexName);
                   
    }

```

We would like to **STOP** Elasticsearch **REFRESHING** the Index until we have finished indexing all the batches. Then enable and refresh the index.

How can we achieve this with the NEST library

Many thanks

To disable the refresh interval

```
client.UpdateIndexSettings("index-name", u => u
    .IndexSettings(i => i
        .RefreshInterval("-1")
    )
);

```

To enable the refresh interval again and set it to 1 second

```
client.UpdateIndexSettings("index-name", u => u
    .IndexSettings(i => i
        .RefreshInterval("1s")
    )
);

```

Async variant of `UpdateIndexSettingsAsync()` can also be used

Thank you very much Russ,  
Any idea on my other question as to can one find out which field in the  
document matched the query.

Many thanks
