Hi,

I'm using for the first time the logstash-filter-elasticsearch plugin version 2.1.1.  
How can I specify which index to query?

What is the default for this? searching all indexes or only the current index?

An `index` option for selecting the index(es) to search was added in v3.0.0 of the logstash-filter-elasticsearch filter. Prior to that I think it searched all indexes.
