Logstash elasticsearch filter plugin - set index


I am trying to use elasticsearch filter plugin in logstash to query previous messages for the same session.
elasticsearch {
hosts => ["localhost"]
query => "tags:Connection_new AND session_id:%{[session_id]}"
fields => ["logdate", "started"]
if ![started] {
mutate {
add_tag => "Connection_new"

However this query returns error for .kibana index [No mapping found for [@timestamp] in order to sort on].
Is it possible to set index for query to search on using this plugin?

Thank you very much for any help.

I've the same problem. Before version 2.0 you could add the index in the host but today it is no longer possible. I found this page: Specify index when using elasticsearch logstash filter but I haven't tried to patch the plugin.
