we have 4 different domain for the same site and all have same content and everything so it was making duplication of our website so i suggested to add either robots.txt or to redirect every domain to main site and finally it was decied to add robots.txt and our system admin did mistake of adding robots.txt file to main site which was made to stop all the spiders crawling other domains, and it was there for a week .
so google removed our site from database.. now even when i do URL search nothing comes up, i lost PR which i achived so far, and everything is gone.
i need help in this , if you have any tips related to how to get site back in google soon..
please give me...
