One is an open source search engine and one is a closed source hosted 
NLP service you pay for. I think you're comparing chalk and cheese here: 
you would use a NLP service to enhance the source data before indexing 
with something like Solr, or extract information from a query before 
searching. Although Solr does contain some classification features it 
doesn't contain any NLP features - although as my colleague Liz writes 
you can now easily integrate Solr & OpenNLP, another open source 

By the way are you aware that NHS Wales are using Solr to power their 
patient records service?
