Partial fix of #444

It is possible to implement what the web does but that adds additional resources which I believe is not justified. Filtering is meant to be precise. Even hiding the entire block that you still would like to take a look at the content, then why would you set up a certain filter then.

Though showing the matched filter is still useful.
