We're considering Elasticsearch for our data search solution and are wondering about the latency between the request to index a document and when the document becomes searchable. How long after a request to index a document is received will that document be surfaced via the search APIs? I recognize that this is a relatively vague question and depends on a variety of factors but I'm looking to get an idea at least of the order of magnitude. Are we talking seconds or minutes? We would be expecting to generate a few dozen indexing requests per second at peak and would like to see the documents searchable as quickly as possible. Also is the indexing request a blocking call? Does Elasticsearch return "SUCCESS" once the request is received or does it wait until the document has been indexed successfully? ---

Take a look at [https://www.elastic.co/guide/en/elasticsearch/guide/current/near-real-time.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/near-real-time.html) Once a document is indexed it is usually available for search within a second or so. You can change the setting a bit, but it could impact performance. I believe ElasticSearch will return a success message once the request has been written to the primary and replica shards. Then a second or so later it will become searchable. However I don't remember where I heard that so I might be wrong. ---
