First thing to do is attach &query=debug to your queries and look at the parsed output.
Second thing to do is look at the admin/analysis page and see what happens at index and query time to things like o'reilly. You have WordDelimiterFilterFactory configured in your query but not index analysis chain. My bet on that is that you're getting different tokens at query and index time... Third thing is that you need to escape the & character. It's probably being interpreted as a delimiter on the URL and Solr ignores params it doesn't understand.
