You can commit different documents to the same index. ES will store the type in a special key named _type.
Awesome screencast and with great timing too. My company is switching from Solr to ES just as I type. =)
ElasticSearch is (near) real time and has built-in sharding and clustering support.
Thanks a lot for those screencasts. =D
