It hasn't worked for me for a long time. I keep getting three Russian LJs as results, usually the same three. Yandex used to be the in-house search engine. Now the default is general on-LJ and generally online Google. I've googled "yandex" and used it to search LJ, but the results are laughable. I've just stopped using it and use Google instead--at least it sort of works, unless what you're looking for on LJ is flocked.

They keep improving things. They're not improving things.
