Our index size seems to grow and grow over time. I assume this is due to versioning. I don't care about having multiple versions of a document. How can I just turn it off? -- ---

In fact, ES doesn't store multiple version of docs but use a version number for optional concurrency control. See [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/index_.html) [http://www.elasticsearch.org/guide/reference/api/index\_.html](http://www.elasticsearch.org/guide/reference/api/index_.html) That said, you can call Optimize API to optimize your index. See : [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/admin-indices-optimize.html) [http://www.elasticsearch.org/guide/reference/api/admin-indices-optimize.html](http://www.elasticsearch.org/guide/reference/api/admin-indices-optimize.html) Are you creating and deleting many documents?

Ah - thanks for the clarification. Our rough numbers are something like the following: - 20 million docs - 500,000 re-indexes per day - 10,000 deletes per day (but occasionally up to 1 million) - 10,000 new docs per day Is the optimize API something I should be working in to our regular process? -- ---

I understand the "modern way" to do that is not to optimize, but to modify the merge policy which is used to automatically combine the low-level Lucene segments as needed. The values that trigger a merge and how to re-merge are all defined by the merge policy. I too was all worried about optimize until I saw the merge policy kick in and clean things up. What you want is for deleted documents to end up in segments that are small enough to likely eventually either completely disappear or get merged together with others thus dropping the deletes and even elimating whole segment files, but with some balance between too many segments, and no segments that ever get merged together. -Paul On 10/19/2012 7:31 AM, Cailin Nelson wrote: > Ah - thanks for the clarification. > > Our rough numbers are something like the following: > > - 20 million docs > - 500,000 re-indexes per day > - 10,000 deletes per day (but occasionally up to 1 million) > - 10,000 new docs per day > > ## Is the optimize API something I should be working in to our regular process? -- ---

As Paul said, there is a background merge process running all the time, with reasonable defaults, so you don't need to run the optimize API in a scheduled manner at all.
