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

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

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?

Have a look at "index": "analyzed|not\_analyzed|no" on this page:
