I'm trying to find a good example of how to use the Query String for the 'Group By Filter' in the Time Series Visual Builder.

Essentially, I'd like to Filter upon a basic Count aggregation, and utilize the Query String field, and do this a couple of times for different values.

I cannot find examples on syntax, or anything. If I wanted to Filter based upon a field having a value of '50', what would that look like in the Query String?

Hi,

TSVB (Time Series Visual Builder) uses Lucene query syntax.  
So this would be field\_name: 50

Here are our docs for Query syntax: [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#query-string-syntax)

Here is the first part of blog series which is going to explain TSVB: [https://www.elastic.co/blog/master-time-with-kibanas-new-time-series-visual-builder](https://www.elastic.co/blog/master-time-with-kibanas-new-time-series-visual-builder)

Cheers,  
Bhavya
