Thanks, @felixcheung. When I am looking at the discussions again today, I
find I am more clear about your suggestions. But actually, truncating very long
queries is not because they are not visually pleasant to be displayed on the
page, but it may take too many resources to store and transfer such a long
unlimited string. So the queries longer than 1000 chars are truncated after
parsing, which will never be recovered. So the idea of clipboard may not be
used to resolve it.
But still, I believe the clipboard is a good idea. I do think we could
extend the limit to 10k chars instead of 1k if we add a clipboard later.
