Oh, come on. No need for Power Search here. Have you tried using the word "Chromium" in said obvious search box that you mention ?

It returns exactly four threads with the word in the title, with the original one in second position, this duplicate being third, and the two others much further down the page.

Which means that a basic search *before* creating this dupe would have shown the existence of the original in plain sight, as the first or second hit. Moreover, I just tried creating a new topic with "Chromium" in the title, and before I could enter a word it displayed a list of similar topics, in which the original comes first with its 189 posts.

So yes, forum search is not always very effective for difficult queries, but in this case your argument is hot air: it's just the chair-to-keyboard interface being exceptionally dumb.
