How to index MySQL from ElasticSearch

view story

http://serverfault.com – Im trying to add some full text searching to my LAMP web application. Ive come across ElasticSearch and I like what it has to offer. I have read the guides and understand how to index a single item by using curl -XPUT http://localhost:9200/. But how can I index an entire MySQL database? I cannot seem to find anywhere on the web that explains how to do this. Any ideas? (HowTos)
