There is a search in the terms page that for filtering
the search position is on the right part and there is enough space on the left as well. This row is only contains the search input.

So, if you are typing a long text, we need to do horizontal overflow all the time.

Solution 1: The Search input can be full width initially.
Solution 2: The Search input can be full width on focus.
Solution 3: you can create your own solution ;)
