Solr and explaining "AND" and "OR"

I was asked by a client to explain Relevancy as they didn't understand why adding an additional word to their query was actually causing a result to not show up (at least at the top of the list) as they expected. It turned out the actual discussion wasn't about relevancy at all, but And and Or and how they are used in Solr.
