Need mapping help with unit test in java api

Craig_Brown · May 24, 2012, 9:36pm

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

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!

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
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
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
ces/es1/twitter/tweet.json )

Hope this could help you to solve your issue.
David.

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.

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();
