In one of my previous jobs I was in charge of developing the whole search strategy for a company. We chose solr and was very happy with it. Solr and Elastin are Lucene based but Solr and Lucene are now one repo. Solr changed a lot in last few years and is very flexible in what you can do with it. But it's definitely hardest one to setup out of these (aldo they did a lot of work to make it easier for the most common usecaees).
I would go for solr for bigger complex projects with a lot of content types, etc..
For smaller sites and simple search on those I would go for something little bit eaiser.
