Hi folks, I've been trying to figure out the default analyzer for '\_all'. At first, I was simply thinking that it would be the standard analyzer. But as my testing shows, it's not the case at all (stop words are kept?!)? After some testing, it would appear to be using the standard tokenizer, with a lowercase filter. I would have tried to find out more myself... but it's not as if you could query the mapping and try to see the result for yourself (it doesnt show for '\_all'). Does anybody have any more info? Is it using any provided analyzer? thanks, -jf -- He who settles on the idea of the intelligent man as a static entity only shows himself to be a fool.

It depends on your elasticsearch version I guess as in 1.0, standard analyzer does not remove stop words anymore. -- David Pilato | Technical Advocate | [Elasticsearch.com](http://Elasticsearch.com) @dadoonet | @elasticsearchfr Le 13 mars 2014 à 08:06:55, Jeffrey 'jf' Lim ([jfs.world@gmail.com](mailto:jfs.world@gmail.com)) a écrit: Hi folks, I've been trying to figure out the default analyzer for '\_all'.

I see! I guess the docs had me confused (or more like, I read the description, but didnt go on to read into the details of the settings, argh). So the standard analyzer is indeed used for '\_all'? thanks, -jf On Thu, Mar 13, 2014 at 3:30 PM, David Pilato [david@pilato.fr](mailto:david@pilato.fr) wrote: > It depends on your elasticsearch version I guess as in 1.0, standard > analyzer does not remove stop words anymore. > > -- > David Pilato | Technical Advocate | [Elasticsearch.com](http://Elasticsearch.com) > @dadoonet | @elasticsearchfr > > Le 13 mars 2014 à 08:06:55, Jeffrey 'jf' Lim ([jfs.world@gmail.com](mailto:jfs.world@gmail.com)) a écrit: > > Hi folks, I've been trying to figure out the default analyzer for > '\_all'.

Hi, I have a question about memory usage. My cluster has 1 master and data node and 3 data nodes. Each have 6 GB heap size (which is nearly half of the machine). I have 250 shards with replicas and I have 600 GB data in total. When I start the cluster, I can use it for 1 week without any problem. After a week, my cluster begins to fail due to low memory (below 10%). When I restart all the nodes, everything is fine, again. Free memory goes up to 40%. And, it fails again 1 week after the restart. I think some data is remaining in the memory for a long time even if it is not used. Is there any configuration to optimize this? Do I need to flush indices or clear cache periodically? Thanks, Umutcan -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
