What is wrong with search?

I was unable to use it for many days now.
Has it been fix yet?

The board often suffers DDOS attacks, plus, as quoted by Inde, we have thousands of people trying to access the board all at once. This extreme traffic leaves the search engine down quite often. Unfortunately there's not much to do but wait and check the search engine from time to time.

In truth, the engine has been up more than around the first DDOS attack - from which the engine was down for days, maybe weeks.
