We do have a query perf issue which I asked in another topic:

> [@ES query performance when searching on filed with wildcard in field name](https://discuss.elastic.co/t/es-query-performance-when-searching-on-filed-with-wildcard-in-field-name/75658):
>
> I saw significant performance difference between searching on field with exact field name and searching on field with wildcard suffix i name. Following is my mapping: PUT /myindex { "mappings": { "docs": { "Locale": { "type": "text", "fields": { "lowercaseraw": { "type": "text", "analyzer": "lowercase\_keyword" } }, "analyzer": "standard" }, …

Could you please take a look?
