 The Elasticsearch integration depends on an external indexer. We ship an [indexer written in Go](https://gitlab.com/gitlab-org/gitlab-elasticsearch-indexer). The user must trigger the initial indexing via a rake task but, after this is done, GitLab itself will trigger reindexing when required via `after_` callbacks on create, update, and destroy that are inherited from [/ee/app/models/concerns/elastic/application_versioned_search.rb](https://gitlab.com/gitlab-org/gitlab/blob/master/ee/app/models/concerns/elastic/application_versioned_search.rb).
 
-After initial indexing is complete, updates proceed in one of two ways, depending on the `:elastic_bulk_incremental_updates` feature flag.
-
-If disabled, every create, update, or delete operation on an Elasticsearch-tracked model enqueues a new `ElasticIndexerWorker` Sidekiq job which takes care of updating just that document. This is quite inefficient.
-
-If the feature flag is enabled, create, update, and delete operations for all models except projects (see [#207494](https://gitlab.com/gitlab-org/gitlab/issues/207494)) are tracked in a Redis [`ZSET`](https://redis.io/topics/data-types#sorted-sets) instead. A regular `sidekiq-cron` `ElasticIndexBulkCronWorker` processes this queue, updating many Elasticsearch documents at a time with the [Bulk Request API](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html).

 Search queries are generated by the concerns found in [ee/app/models/concerns/elastic](https://gitlab.com/gitlab-org/gitlab/tree/master/ee/app/models/concerns/elastic). These concerns are also in charge of access control, and have been a historic source of security bugs so please pay close attention to them!
