Hi Ben, You'll have to reindex your data. One way to do it is to scroll through the existing index and make a new one with the same data, then delete the initial index. Here's a blog post by Zachary with some code that should help: [http://euphonious-intuition.com/2012/08/reindexing-your-elasticsearch-data-with-scanscroll/](http://euphonious-intuition.com/2012/08/reindexing-your-elasticsearch-data-with-scanscroll/) Best regards, Radu On Thu, Dec 5, 2013 at 1:24 PM, Ben Ryan [argaric@gmail.com](mailto:argaric@gmail.com) wrote: > Hi, > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/088474b4-ed13-4ef0-b7d0-b7e7d2acbf83%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/088474b4-ed13-4ef0-b7d0-b7e7d2acbf83%40googlegroups.com) > . > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- Performance Monitoring \* Log Analytics \* Search Analytics Solr & Elasticsearch Support \* [http://sematext.com/](http://sematext.com/) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
