I have some doubts in doc_value.
current version is elasticsearch 1.3.7, we are planned to upgrade our elasticsearch instances.
Before that we need to clear mapping conflicts, for that we are created new mapping and re indexing data.
In new mappings we are planned to enable "doc_values":true in all fields is it OK?
- doc_value supports all fields?
- Any issues with doc_values?
- doc_values using disk while aggregating data, how long it persist on disk? and how to manually remove that data ?
