To use the `ElasticStore` (hereby Elasticsearch) as a drop-in replacement for the existing `SQLStore` based `QueryEngine` the following settings require some changes:

- Set `$GLOBALS['smwgDefaultStore'] = 'SMW\Elastic\ElasticStore';`
- Set `$GLOBALS['smwgElasticsearchEndpoints'] = [ ... ];` (see the [documentation][es:conf:hosts] for how to maintain inline or extended host parameters as it takes the same attributes as outlined in the official documentation, or see a [configuration example][conf:example])
- Run `php setupStore.php` or `php update.php`
- Rebuild the index using `php rebuildElasticIndex.php`

It is recommended to consult the [official][es:conf] documentation for Elasticsearch specific settings and configurations.

## Topics

- The [replication section][section:replication] contains details about how indexing is expected work in connection with Semantic MediaWiki and any peculiarities in regards to the replication with Elasticsearch. It further provides a passage on indexing "unstructured" content from either an article or file.
- The [search section][section:search] highlights the use of the `#ask` syntax in combination with the Elasticsearch specific query execution.
