The Related Search Operator Is Broken for Some Sites

Looks like the related: search operator might be broken for some sites.

From an SEO point of view this is a handy operator to find other sites that are similar to the one you provide, good for competitor research. Say you want to find out similar sites to ahrefs.com. Now it appears that they don’t work for all sites here is an example where it does not provide any results time.com.

I hope it does not end up like the ~ operator that got dropped a while back.
