========================
Admin Indices Open Close
========================

The open and close index APIs allow to close an index, and later on opening it. A closed index has almost no overhead on the cluster (except for maintaining its metadata), and is blocked for read/write operations. A closed index can be opened which will then go through the normal recovery process.


The REST endpoint is **/{index}/_close** and **/{index}/_open**. For example:


.. code-block:: js

    curl -XPOST 'localhost:9200/my_index/_close'
    
    curl -XPOST 'localhost:9200/my_index/_open'
