Use a comma-separated list to support clustering (for example, `http://host1, https://host2:9200`). If your Elasticsearch instance is password-protected, use the `Username` and `Password` fields described below. Alternatively, use inline credentials such as `http://<username>:<password>@<elastic_host>:9200/`. | | `Username` | The `username` of your Elasticsearch instance. | | `Password` | The password of your Elasticsearch instance. | -| `Number of Elasticsearch shards` | Elasticsearch indices are split into multiple shards for performance reasons. In general, you should use at least 5 shards, and indices with tens of millions of documents need to have more shards ([see below](#guidance-on-choosing-optimal-cluster-configuration)). Changes to this value do not take effect until the index is recreated. You can read more about tradeoffs in the [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/scalability.html). | -| `Number of Elasticsearch replicas` | Each Elasticsearch shard can have a number of replicas. These are a complete copy of the shard, and can provide increased query performance or resilience against hardware failure. Increasing this value increases total disk space required by the index. | +| `Number of Elasticsearch shards and replicas per index` | Elasticsearch indices are split into multiple shards for performance reasons. In general, you should use at least five shards. Indices with tens of millions of documents should have more shards ([see the guidance](#guidance-on-choosing-optimal-cluster-configuration)). Changes to this value do not take effect until you re-create the index. For more information about scalability and resilience, see the [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/scalability.html). Each Elasticsearch shard can have a number of replicas. These replicas are a complete copy of the shard and can provide increased query performance or resilience against hardware failure. Increasing this value increases the total disk space required by the index. You can set the number of shards and replicas for each of the indices. | | `Limit the number of namespaces and projects that can be indexed` | Enabling this allows you to select namespaces and projects to index. All other namespaces and projects use database search instead. If you enable this option but do not select any namespaces or projects, none are indexed.
