# refreshIndex

When writing or deleting documents in Kuzzle, the update needs to be indexed before being reflected in the search index. By default, this operation can take up to 1 second.

Given an index, the refresh action forces a refresh, on it, making the documents visible to search immediately.

A refresh operation comes with some performance costs.

From elasticsearch documentation:
"While a refresh is much lighter than a commit, it still has a performance cost. A manual refresh can be useful when writing tests, but don’t do a manual refresh every time you index a document in production; it will hurt your performance. Instead, your application needs to be aware of the near real-time nature of Elasticsearch and make allowances for it."
