Search on Habré

Once again I was faced with the problem of searching on the hub I wanted to publish a link to interesting news, searched, rummaged - there is none. Published ... Showered minus. I think what’s the matter, not a single angry kament. Then I look in similar publications, the first link to the same news :( Why so? Why can’t I index the search as the article arrives? How do I know if my news is first?
