When I do search for e.g. "configuration backend" I get broken links.
They are broken only on latest version. On v1_6_0 and when I'm building
and running Sphinx under my desk all is ok. I see that search engine
is different in RTD than in vanilla Sphinx.

Expected Result

When I do search in latest version I get broken links:
https://kea.readthedocs.io/en/latest/search.html?q=configuration+backend&check_keywords=yes&area=default

Actual Result

When I do search in v1_6_0 version I get ok links:
https://kea.readthedocs.io/en/v1_6_0/search.html?q=configuration+backend&check_keywords=yes&area=default#
