Hi,

I am on Logstash 2.4 and trying to query only selective fields **["@timestamp", "user"]** from Elasticsearch 2.4 using the **input plugin "elasticsearch"**.

Using the search API for Elasticsearch, I could search for specific fields however using the elasticsearch input plugin, I could only figure out that the "query" either takes a value in a field for a **match** or **match\_all** which returns all possible matches.

What I am expecting is to see **all the values** for the fields **["@timestamp", "user"]** from the events so that I can further process them writing to the disk.

Could any one suggest the best way to deal with this please ?

Thanks

What does your configuration look like? What results are you getting? What results did you expect?
