[support] Trying to Understand How Data in the DB is Exposed to Search

Gang, Trying to understand how search works, both Google and Solr. So lets say I have a node/1234. There are no links to it on example.com. However, links to it will dynamically show up in a view if the right choices are made by a user via exposed filters. My guess is this won't be exposed to Google but would be exposed to Solr. Anybody know? Thanks, Shai
