Improved search for posts when merging

Good day!

Issue description

If you have more than one post on the same topic on your board, you merge them, and generally, there are no problems. However, when there are 3-4 or more such posts and they appear at different times, problems begin to arise when trying to merge them. Specifically, the issue lies in searching for posts. For example, you want to merge posts, and this is already the third post on a similar topic. You find posts by keywords, and it's unclear which one is the main post and which ones are those that you've attached to the main post.

Suggestion

Either simply do not display in the search those posts that have been attached to the main one, but this is not a very good solution. Alternatively, at least mark the main post and those attached to it with a color.
