Thanks John, and Mary Joe Yeah it's definitely more about "relevance" than ES or Solr. So the choice in search engine is more an implementation detail. We chose ES because it's more book/educational friendly, not necessarily because it's the best choice as a search engine. It's query language is closer to Lucene, so it helps for educational purposes without having to teach readers Java and Lucene. We can also do everything (schema, queries, etc) in JSON in an ipython notebook, which is very conducive for book content.
If you're interested in the pros/cons of Solr ES around relevancy, I definitely tried to document where we hit the edges of ES's capabilities in blog posts like http://opensourceconnections.com/blog/2015/12/15/solr-vs-elasticsearch-relevance-part-one/ http://opensourceconnections.com/blog/2016/01/22/solr-vs-elasticsearch-relevance-part-two/ I was going to write a part 3 about plugins, but Flax's post seems to summarize this well enough so that I'm not sure I'll need to! http://www.flax.co.uk/blog/2016/01/27/fun-frustration-writing-plugin-elasticsearch-ontology-indexing/ (TLDR: Solr is easier to write plugins for) Anyway as per the book. We try to do our best to map what we do to Solr in a fairly detailed appendix. Let us know how well you think our strategy works!
