I wanted to test one of my parked domains with Namedrive
and i saw that even if you type the whole domain name as
keyword google doesnt include it in the results.
Anyone who knows something more?

Most likely that your domain hasn't been indexed by Google yet. Answering your question I would say that, yes Google search engine doesn't like multiple domains for one website, parked domains, redirections, etc. For this reason I usually recommend people to have no more than one domain for a website.

Google finds websites by following links. If there are no links to your parked domain then Google won't find it and index it. Google has nothing against parked domains, they even offer "AdSense for Domains" for parked domains, but websites with no content - just ads - will not rank well in the search engine results.

I think that something goes wrong with Namedrive..
i have domains parked with Sedo for just three days
and they are already indexed and domains parked with
ND for 2 months and nothing yet..:mad:

If there are no links to your parked domain then Google won't find it and index it. Yes, put more incoming links and submit a website to Google search engine manually if you wish to speed up the procedure of domain indexing.
