Re: doc_values for non analyzed fields
So,
There is no sense to reindex everything just to set doc_value to non
analyzed fields.
Non indexed fields are not in the field data anyway
Right ?

Re: doc_values for non analyzed fields
Doc values cannot be used to fetch values, they are only used for sorting,
scripts and aggregations. It is like fielddata, but computed at indexing
time and stored on disk.

doc_values for non analyzed fields
Hi,
Will it make any difference in terms of field data memory, if I set the
field data format to doc_values for all fields that have mapping "index" :
"no" ?
Are these (non-analyzed) fields ever loaded in memory on first place ?
Example field mapping :
"rot": {
"index": "no",
"type": "integer"
}
I don't need to query on these fields, but i need to fetch them .
Any negative impact on my queries ?
Thank you
Georgi
