Does Lucene/Solr do, or can it do, any sort of increase on relevancy depending on which search result a user picks?
I don't think it's Lucene or Solr's job to know anything about what users do with the results it generates. You may want to look at the Nutch (web search) project, but even there i do not believe there is any support for relevance feedback.
As a matter of fact, updating only single field in a document is not supported in Solr or Lucene last I checked -- you have to post the whole document (with change) back in.
In one web application I work on, a rock star Solr dev made a special SQL request handler (fork of the Solr RequestHandler) to set votes and hit counts per Solr ID. The SQL table is adjoint to the Solr index. SQL is at the moment better suited for this type of task.
