Search panel makes infinite loop requests in main page

[texnicii]

On the main page request to "https://www.php.net/js/search-index.php?lang=ru" is too many repeating and looks like infinite loop.

I have cleared browser cache and refresh the main page, it repeated.

UPD: The same in incognito mode (even just not typed something into search form)

Indeed! Does not happen for "de" (haven't checked others).

I think it's incorrectly being cached without content, so it's causing duplicate requests.

It's back to normal now.
