Facet pages bring site down because of bots We have a search page that uses facets and recently our website has been going up and down.  When looking at the logs I noticed that bots (Bing, Ahrefs, etc..) are hitting these facetted pages a lot.  Since the facetted pages are not cached I think it is causing this issue. 

I did add Search-specific caching but that did not help.

I have seen these related issues with caching and facets:


facets will disappear, when you enable caching for a views page
Facet blocks not displayed with cached Search API View
Facet blocks disappear when Views caching is enabled


Has anyone else ran into an issue like this?  For now I blocked all bots from accessing the facetted urls (so they will still be able to see the main search page).
For example, my facet page path starts with /library.  I created a Firewall rule in Cloudflare to block anyone visiting a page that contains /library/ so a facet result page like /library/xxx/bbb/ccc and is a known bot will be blocked.
