Hi ES community,

I have one question recently i have done reindexing then ES up-gradation from v6.8.23 to v7.17.9. After this operation i noticed some error in elastic-search.

```auto
Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations a
re disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [TARGET_NAME] in order to load field data by uninverting the inverted index.

```

I would like to know How can i change this default option and what would be the step?

Thanks  
Sonu

Hi @sonujatav35,

It looks like you are performing aggregations (perhaps in some dashboard visualizations) using a `text` type field rather than a `keyword` type field. Are you able to change your query/ visualization to use the `keyword` field instead?

Thanks for the suggestion as of now I have not updated my query but let me try update it accordingly. If i do not want to change Dashboards visualizations query then this(fielddata=true) option i have to append to my query?

You would need to amend the index mapping. There is an [update example here](https://www.elastic.co/guide/en/elasticsearch/reference/8.8/text.html#enable-fielddata-text-fields). However I would read the [caveats listed here carefully](https://www.elastic.co/guide/en/elasticsearch/reference/8.8/text.html#before-enabling-fielddata) as there is a memory impact of enabling this setting.
