How do you print something while doing the query and waiting for the results?
I saw some pages that display something like: "This page will be
updated in X seconds to show the results" (X is an estimated time
depending of server load), after a JS countdown, it refresh itself and
show the result or another "This page will be updated in X seconds to
show the results".

The usual way is by "client pull": send the content you want the user to see, and include a Refresh: header - the easiest way is to include a META tag in the html content <head> section like

<meta http-equiv="refresh" content="N; URL=other-web-address">

So the page can continually check whether the user's job is finished, if it isn't just sending out the same content and then when it is printing the details.
