To these responses, I would also add: extremely easy to install and "configure" 
-- that is, NO configuration is required to get it running out-of-the-box 
(including schema definitions, servlet containers, etc.)  This alone was what 
drew me to ES in lieu of Solr way back, though I don't know if it has changed 
in Solr 4.
