Hi all, I have a varied data stream that may change without substantial or any warning from the source. I'd like to be able to make it so that if a key name contains the string "url", that key will be not\_analyzed. Is that possible to do with the config/default\_mapping.json? Basically, I want to be able to define in default\_mapping.json If not, can I define an explicit list of fields in default\_mapping.json? I tried the following and if I add a url field to a new index it's not marked as not\_analyzed. { "_default_" : { "url" : {"type":"string", "index":"not\_analyzed"} } } I also tried the following { "_default_" : {}, "url" : {"type":"string", "index":"not\_analyzed"} } which results in: org.elasticsearch.index.mapper.MapperParsingException: mapping must have the `type` as the root object at org.elasticsearch.index.mapper.DocumentMapperParser.extractMapping(DocumentMapperParser.java:261) at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java:169) at org.elasticsearch.index.mapper.MapperService.parse(MapperService.java:387) at org.elasticsearch.index.mapper.MapperService.merge(MapperService.java:195) at org.elasticsearch.index.mapper.MapperService.documentMapperWithAutoCreate(MapperService.java:416) at org.elasticsearch.index.shard.service.InternalIndexShard.prepareCreate(InternalIndexShard.java:319) at org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java:211) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java:533) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction$1.run(TransportShardReplicationOperationAction.java:418) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) This error makes me think that I can't predefine fields in default\_mapping.json like I was hoping, is that accurate? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, Take a look at dynamic templates[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-root-object-type.html#\_dynamic\_templates](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-root-object-type.html#_dynamic_templates) .
