Dynamic mapping questions

Elastic Stack Elasticsearch
1

Hi,

Two questions regarding the mapping process.

  1. I see for the object type you have the field enabled in case you don't want to index it in
    subsequent calls. How can you not index a core type field. Meaning you have an initial mapping where you set your fields.
    But some later call to index can have a core type field that I don't want to index. As it is now, correct me if I'm wrong, it
    will get dynamically mapped. How can I avoid that.

  2. If I change the mapping I have for a document by adding a new field, dynamically or not, it will cause a re-indexing of the already indexed documents?

Thanks
stelios

    You can set the dynamic flag to false on the root object mapping.

    documents?
    No, you don't need to reindex. Introducing new fields does not require reindexing.

I think I didn't phrase it correctly

consider this json

{
"analysis": {
"audio_info": {
"1_0": {
"successful": true,
"data": {
"bits": 16,
"bitrate": 689.1609186183296,
"channels": 1,
"duration": 9.351,
"samplerate": 44100,
"type": "wav"
}
}
}
}

How can I not index the field "successful". When I do a mapping and not
include this field but then index a document that has this
field then it gets mapped dynamically. Of course I can set dynamic mapping
off and it will work as I want but there are other cases where dynamic
mapping is handy.

Thanks
Stelios

Just to clarify I know that I can use "enabled" : false in the "1_0" object
so it will not map the "successful" field but it won't map any other fields
as well. What I really need is to do something like "successful" :
"not_mapped". Is this possible at the moment?

thanks

Have a look at "index": "analyzed|not_analyzed|no" on this page:
