I'm trying to use the Elasticsearch filter in my logstash configuration to search a specific index for a term. I need help building the query. Would the following be valid?

{  
"indices" : {  
"indices" : ["index1"],  
"query" : {  
"term" : { "term1" : %{[event\_field\_name]} }  
}  
}  
}

The documentation doesn't seem to give much info on more complex DSL queries:

[https://www.elastic.co/guide/en/elasticsearch/guide/master/search-lite.html](https://www.elastic.co/guide/en/elasticsearch/guide/master/search-lite.html) should help, there are also other chapters that will help 🙂

Thanks for the reply. That link didn't say anything about specifying an index. I even looked through the reference docs for Query String Query, which your link referenced. I didn't notice any way in search lite to specify index. I know this can be done in the request body search API.

Any other references are appreciated.
