Ability to filter/search comments on traces

[jakob-squadformers]

Describe the feature or potential improvement

I really like Langfuse's comments feature on traces since it facilitates collaboration with stakeholders. However, I am missing the ability to find comments among the large amount of traces that can accumulate. From my current knowledge, I have to search traces one by one to find a comment. Potential ideas to address this:

• A filter condition based on comment count
• Extending the Search functionality in the Traces overview to "Search Comments", this could be super helpful for searching a coworker's name and then getting all the traces they commented on

Upping this. How do I mark traces otherwise?

Please allow to filter out traces by availability of comments since it's the most essential use case:

1. Subject matter expert opens Sessions containing production and just browses them one-by-one checking if output of the system is OK.
2. When found something, they leave a comment for the corresponding trace.
3. After finishing the review, they want all those traces with comments added to be added to a separate dataset so that evals can be developed confirming the issue exists.

Currently, it's impossible to filter out traces with >= 1 comment in them which makes work unintuitive and forces them to first come up with a new dataset even before starting review and only then to filter them out.

If there is a more natural way of doing what we want to achieve, please let me know.
