Foreclosure documents

[B B]

I'm very new to this...still trying to find my first house to invest in. The county I'm interested in has its records online, but I'm not sure what document type is filed when the foreclosure process starts. I can't find anything about Notice of Default or Notice of Sale. I don't actually live in the county I'm interested in, so I can't go down to the courthouse and look up the docs. Any suggestions on what to look up?
