All I am using Embedded ElasticSearch On JAVA API. It is creating indexes correctly. Once I create the index, I see a folder "elasticSearch" under my home directory. But even after I remove this "elasticSearch" folder from my home directory, it still performs the searches. Is it being stored somewhere else too? Sometime while debugging I need to get rid of the contents of this elastic folder, and start all over again. So, is there any other place I need to remove elasticSearch indexes on my box? Thanks ---

Hi, check here [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/setup/dir-layout.html) for folder locations used by ES and how they can be configured (some of them support multi locations). You need to know how these locations are configured in your case. The chance is that you are using in-memory indices which means that Lucene segments are not found on the disk. You can also use gateway of type none (which again means the gateway data is not stored on the disk). This is typically used during unit tests. You can find a lot of examples in ES unit test code, or you can check one example that I uploaded to github some time ago: > > > //github.com/lukas-vlcek/elasticsearch.demo/tree/master/src/test/java/org/elasticsearch/demo Check both abstract and basic test class, how the paths are configured and how I clean up after test.

This is how I'm doing in java api: ImmutableSettings.Builder settings = ImmutableSettings.settingsBuilder(); settings.put("path.home",System.getProperty("user.home")+"/elasticSearch"); settings.put("number\_of\_shards",1); settings.put("number\_of\_replicas",0); Node node = NodeBuilder.nodeBuilder().settings(settings).clusterName("firstCluster").node(); Client client = node.client(); client.admin().cluster().prepareHealth().setWaitForYellowStatus().execute().actionGet(); client.prepareIndex("searchdata", "exhibitor", "9999").setSource("My data information").execute().actionGet(); When I use this to create node and index, it creates the folder "elasticSearch" under my home directory. But even after I remove "elasticSearch", it still does search. So I have no clue where it is grabbing the indexed data after I have completely deleted "elasticSearch". Any suggestions? Thanks ---

Hi, it is hard to answer this question without complete code example but may be the reason is that the index data are still in memory because it hasn't been flushed yet.

Once the indexes are created, I am doing client.admin().indices().prepareRefresh().execute().actionGet(); and it does flush. After I have deleted elasticSearch, I was still able to perform search. I have no clue where it is grabbing data for this search. I have killed my JVM too and it still does search without elasticSearch being existed anywhere. So I ended up restarting the machine. With no elasticSearch folder and restart of my machine, it did not do a search. This makes me believe that the index is also stored somewhere in the memory with my settings. Here is my settings for a reference: ImmutableSettings.Builder settings = ImmutableSettings.settingsBuilder(); settings.put("path.home",System.getProperty("user.home")+"/elasticSearch"); settings.put("number\_of\_shards",1); settings.put("number\_of\_replicas",0); Node node = NodeBuilder.nodeBuilder().settings(settings).clusterName("firstCluster").node(); Client client = node.client(); client.admin().cluster().prepareHealth().setWaitForYellowStatus().execute().actionGet(); client.prepareIndex("searchdata", "exhibitor", "9999").setSource("My data information").execute().actionGet(); How do I prevent it NOT to be stored in memory? I want indexes to be stored ONLY in my disk location that I have provided under "setttings.put("path.home", System.getProperty("user.home")+"/elasticSearch")"; ---

Hi, based on your description it should be able to situate it using curl command. Can you prepare complete recreation script then?

See [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/help/) regarding recreation script. In other words, put together sequence of shell commands that demonstrate your use case and can be used by anybody to simulate/recreate the issue, it sounds like in your case it would be mostly 'curl' and 'rm' commands.

I have upgraded to elasticSearch 0.19.1 and it seemed to fix the problem for now. If I remove elasticSearch data folder, it does NOT do the search anymore.
