Are you sure that the URL is not indexed at all - or is it just not ranking well? You can do a search oon the URL itself to see if organic search has it. If it isn't there, try using the Fetch as googlebot tool inside your Webmaster Tools account.

but searching his exact title is impossible to find it
Searching an exact title has not been a dependable way for several years now to determine whether a page is in the index. I believe it started happening around the Mayday algorithm update [webmasterworld.com...] back in May 2010, when Google started treated titles conceptually rather than just as literal word strings.
It was widely discussed around then, I believe (someone double-check me on those dates, please), with a long discussion here...
