[xkamil]

Issue submitter TODO list

• I've searched for an already existing issues here
• I'm running a supported version of the application which is listed here and the feature is not present there

Is your proposal related to a problem?

I'm often searching messages by headers and so lot of ppl in my company. The issue is that I always have to remember to write this groovy code. For example: headers.someheader.contains('some-value').
This is frustrating when I do it often

Make search input not only search messages by body containing this search input but also headers values

No response

Version you're running

Additional context

I already did some update in codebase locally and I'm using it.

com.provectus.kafka.ui.emitter.MessageFilters
static Predicate<TopicMessageDTO> containsStringFilter(String string) { return msg -> StringUtils.contains(msg.getKey(), string) || StringUtils.contains(msg.getContent(), string) || msg.getHeaders().values().stream().anyMatch(h -> StringUtils.contains(h, string)); }
