. A Reddit thread states that AJAX populator also does not allow to show all the comments when there are multiple thousands of them.
How do I workaround this restriction and view & search all the comments of the particular video?

Youtube Comments Suite is excellent and can do what you are asking, though if a channel is large it will take a while to pull all of its comments.
Note that you may have to install Java 8 in order to get the program to run.
