Hi Team,
I need to search based on a custom header field, say "context.request.headers.ua-device", I followed below procedure to make that field searchable by changing the index template.
But even after indexing the field (Exclamation mark corresponding to the field, under Discover, has disappeared), If I perform filtering based on this field it is not working.
I even tried changing index setting of the current APM index, settings.index.query.default_field, but not helping.
Kindly help me with this.
