I have just retested and the problem I mentioned before doesn't exist anymore, It has happened around Christmas time, back then, the search returned not very relevant results, Now it shows at the 9th position what google shows at 1th (exactly the article I was searching back then, still as first match on google), but this is a minor difference of order of the first page so I have to say the search is working pretty as expected now. Sorry for not retesting it before making that comment and thanks for keeping the search good. :all right I didn't want to say it but there: russia hypersonic
