Thank you.
now I noticed that my mapping has been working to the index, because when I
search the field which has been enabled false in the mapping cannot be
hitted. So this means that this part is not indexed？ do I understand
correctly?
but here is an another question.
I add a field to be loaded and return in the searchresponse with
addField("myfield"), it seems that there is no required field returned,
here is my code and a screenshot of debug result.
SearchResponse searchResponse = node.client().prepareSearch("pbl")
.setTypes("testpbl")
.setQuery(QueryBuilders.matchQuery("sid","12345"))
.addField("sid")
.setExplain(true)
.setSize(10)
.execute().actionGet();

Just a note to this: There is a big difference between indexing and
storing source document.
Elasticsearch won't touch your source document and will store it as is.
For example, if you use carriage return after each field, you will get it
back when doing get or search operations.

Thanks a lot.
I've read something about mapping and notice there is a "enabled" flag(
Elasticsearch Platform — Find real-time answers at scale | Elastic). I
tried to create an explicit mapping with this flag, here is my code:
String mapping =
XContentFactory.jsonBuilder().startObject().startObject("testpbl")
.startObject("properties")
.startObject("person").field("type", "object")
.startObject("properties")
.startObject("name").field("type", "object")
.field("enabled", false)
.endObject()
.startObject("sid").field("type","string").endObject()
.endObject()
.startObject("message").field("type", "string").endObject()
.endObject().endObject().endObject().endObject()
.string();
node.client().admin()
.indices().prepareCreate("pbl")
.addMapping("testpbl", mapping)
.execute().actionGet();
JSONParser parser = new JSONParser();
Object object = parser.parse(new FileReader("mydoc\\test.js"));
JSONObject jsonData = (JSONObject) object;
node.client().prepareIndex("pbl", "testpbl",
"1").setSource(jsonData).execute().actionGet();
and the test.js is:
{
"tweet": {
"person": {
"name": {
"first_name": "Shay",
"last_name": "Banon"
},
"sid": "12345"
},
"message": "This is a tweet!"
}
}
the question is, it seems that my mapping doesn't work. When I tried to
get my created index and check its content, I still get the name's content
which should not be indexed according to my mapping.
is there any error with my code? I will appreciate for helping.

Hi,
There are a couple of options...
The elasticsearch defaults are great for playing around, but it is almost
always a good idea to disable dynamic mapping and setup explicit mappings(
Elasticsearch Platform — Find real-time answers at scale | Elastic) to configure what
fields get indexed and which ones don't.
The next question is if you want to keep the original JSON or have
elasticsearch strip out elements you don't want. You can accomplish this
with source field include/excludes:
Elasticsearch Platform — Find real-time answers at scale | Elastic
Best Regards,
Paul

I've parsed a json file into an JSONObject and created an index for this

But how can I index only a part of this JSONObject, for instance, only
several fields or nested parts?
Should I extract the required parts of json object and create an another
json object for indexing? I think there should be a better way to do this.
Could anyone give my some advices? Thanks a lot!
