Hi

I want to create a case-sensitive filter inside the Discover screen for a given index data. So far my research has shown that the text search is only case-insensitive (lowercase). I would like to find out how to setup the filter to support case-sensitive or exact-match. Please let me know how. Thanks

note: I also upload the screen-dump of the issue at hand: You can see that the word "info" and "INFO" are being counted for the filter that I hope would only filter out ONLY the word "INFO"

BR/

This stack overflow discussion has some useful ideas on how to approach this - [https://stackoverflow.com/questions/30389495/how-to-implement-case-sensitive-search-in-elasticsearch](https://stackoverflow.com/questions/30389495/how-to-implement-case-sensitive-search-in-elasticsearch)

However, would it make more sense to make the log level is its own field?
