I am using ES version 0.19.7 . It was running fine but now jvm goes out of memory when I use facets. ---

Hello! You probably don't have enough memory to handle your faceting requests. If you have enough memory, you can try increasing it, if you don't and you can sacrifice a bit of performance you can try changing the field data cache type and see if it works for you. You can find more about ElasticSearch cache here: [http://www.elasticsearch.org/guide/reference/index-modules/cache.html](http://www.elasticsearch.org/guide/reference/index-modules/cache.html) and a post explaining a bit > **[ElasticSearch Cache Usage](https://sematext.com/blog/elasticsearch-cache-usage/)** > > We’ve been doing a ton of work with ElasticSearch. Not long ago, we had a few situations where ElasticSearch would “eat” all the JVM heap memory we give it.  It was so hungry, we could not feed it… -- Regards, Rafał Kuć Sematext :: [http://sematext.com/](http://sematext.com/) :: Solr - Lucene - Nutch - ElasticSearch I am using ES version 0.19.7 .

Yes. It could happen. Do you need a more precise answer? Please provide more details about your settings (memory you give to the Jvm), number of docs, number of different terms for the field you want to facet.

I have an index of size 4 gb with 5000 documents and 0 replica .My min heap size is 256m and max heap size of 1g reserved for ES. I want to calculate term facet for all the terms in the docs .Is there any way to do it without going out of memory .

Yes. And, you have 4 gb with only 5000 documents. That means that one document have many many many fields or values. Asking for facets on such huge fields requires lot of memory. David.

Hard to say without any idea of your documents and of your use case. I follow some rules: - I don't facet on fields having to much different values (let say 100 000) - I filter facet on a smaller period (using range filter) - I increase RAM Try with at least 2Gb...
