Search by key does not yield all results

[michalhasko]

We have a pretty big topic that is over 3GB in size with over 2.5M messages in 5 partitions.
When searching for messages using "key equals" search on a specific key, we only get results from 6 days ago (see screenshot). But when we add a "value contains" filter to a unique message identifier that is a part of the value, we do get a newer message (see other screenshot).
The way we found this is that we saw recent messages being logged in our consumer that we couldn't find in the search. But then when we added the value filter, the message would show up.

Steps to reproduce:

1. open a big topic
2. search for messages of a known key using the "key equals" filter

Expected behaviour:
All messages are shown

Actual behaviour:
Latest messages are not shown.

We were able to reproduce this with multiple keys on that topic.
Other way to reproduce is to open the topic, take a key from the tail and search for messages using that key. The message in the tail won't be found.

Version: 0.24.0

Note: Possibly related to #1479

We're experiencing the same on a topic with similar size since AKHQ 0.24.0.
