I have a json mapping file that I user for unit testing that is based on the one I use with CURL. It looks like the java api only accepts the "mapping: {}" section that starts with the type like this: ``` client.admin() .indices() .create(createIndexRequest("myIndex") .mapping("records", "records:{}") ) .actionGet(); ``` I want to add an edgeNGram tokenizer to a field and it looks like it needs to be specified as follows: { "settings" : { "analysis": { "analyzer": { "containsText" : { "tokenizer": "whitespace", "filter": ["lowercase", "autocomplete"] } }, "filter": { "autocomplete": {"type": "edgeNGram", "min\_gram": "1", "max\_gram": "50", "side": "front"} } } }, "mappings" : { "records" : { "properties" : { "name":{"type":"string", "analyzer":"containsText"} } } } } This seems to work from the REST api, but the java mapping api gives the following exception. org.elasticsearch.index.mapper.MapperParsingException: mapping [records] at org.elasticsearch.cluster.metadata.MetaDataCreateIndexService $1.execute(MetaDataCreateIndexService.java:244) at org.elasticsearch.cluster.service.InternalClusterService $2.run(InternalClusterService.java:211) at java.util.concurrent.ThreadPoolExecutor $Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor $Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: org.elasticsearch.index.mapper.MapperParsingException: Mapping must have the `type` as the root object at org.elasticsearch.index.mapper.DocumentMapperParser.extractMapping(DocumentMapperParser.java: 231) at org.elasticsearch.index.mapper.DocumentMapperParser.parse(DocumentMapperParser.java: 141) at org.elasticsearch.index.mapper.MapperService.parse(MapperService.java: 269) at org.elasticsearch.index.mapper.MapperService.add(MapperService.java: 172) at org.elasticsearch.cluster.metadata.MetaDataCreateIndexService $1.execute(MetaDataCreateIndexService.java:241) How can I set this mapping up using the java api so that I can perform some unit testing with ngrams to make sure they are working correctly? Thanks! - Craig ---

Hi Craig, Not sure it will fit to your needs but I wrote something here that create an index using settings.

Interesting. You're using a different api than I am to create the index mapping. I'll need to try that. Thanks for the code resource, very neat and understandable. - Craig On Thu, May 24, 2012 at 3:47 PM, David Pilato [david@pilato.fr](mailto:david@pilato.fr) wrote: > Hi Craig, > > Not sure it will fit to your needs but I wrote something here that create an > index using settings. > [https://github.com/dadoonet/spring-elasticsearch/blob/master/src/main/java/f](https://github.com/dadoonet/spring-elasticsearch/blob/master/src/main/java/f) > r/pilato/spring/elasticsearch/ElasticsearchAbstractClientFactoryBean.java#L6 > 69 > > Also, I define new mappings as follow : > [https://github.com/dadoonet/spring-elasticsearch/blob/master/src/main/java/f](https://github.com/dadoonet/spring-elasticsearch/blob/master/src/main/java/f) > r/pilato/spring/elasticsearch/ElasticsearchAbstractClientFactoryBean.java#L6 > 09 > > ``` > PutMappingResponse response = > > ``` > > client.admin().indices() > .preparePutMapping(index) > .setType(type) > .setSource(source) > .execute().actionGet(); > > Source is a String containing: > { > "tweet" : { > "properties" : { > "message" : {"type" : "string", "store" : "yes"} > } > } > } > (see > [https://github.com/dadoonet/spring-elasticsearch/blob/master/src/test/resour](https://github.com/dadoonet/spring-elasticsearch/blob/master/src/test/resour) > ces/es1/twitter/tweet.json ) > > Hope this could help you to solve your issue. > David. > > > -----Message d'origine----- > > De : [elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com) > > [[mailto:elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com)] De la part de Craig Brown > > Envoyé : jeudi 24 mai 2012 23:36 > > À : elasticsearch > > Objet : Need mapping help with unit test in java api. > > > > I have a json mapping file that I user for unit testing that is based > > on the one I use with CURL.

Ok, figured it out. I tried this one, but must have had the parameters wrong. So it looks like there is a section for settings and another for mappings. The REST call must break those apart automatically. ``` client.admin() .indices() .create(createIndexRequest(index) .settings(settings) .mapping(type, mapping) ) .actionGet(); ``` - Craig On Thu, May 24, 2012 at 4:11 PM, Craig Brown [cbrown@youwho.com](mailto:cbrown@youwho.com) wrote: > Interesting.
