I want to extract Max build\_number from following and apply filter on that max. build number.

Query in dev tools-  
GET logstash-report-2017.10.13/\_search?filter\_path=hits.hits.\_source.build\_number

Result is -

{  
"hits": {  
"hits": [  
{  
"\_source": {  
"build\_number": "271278"  
}  
},  
{  
"\_source": {  
"build\_number": "271317"  
}  
},  
{  
"\_source": {  
"build\_number": "271317"  
}  
},  
{  
"\_source": {  
"build\_number": "271317"  
}  
},  
{  
"\_source": {  
"build\_number": "271317"  
}  
},  
{  
"\_source": {  
"build\_number": "271317"  
}  
},  
{  
"\_source": {  
"build\_number": "271278"  
}  
},  
{  
"\_source": {  
"build\_number": "271278"  
}  
},  
{  
"\_source": {  
"build\_number": "271278"  
}  
},  
{  
"\_source": {  
"build\_number": "271278"  
}  
}  
]  
}  
}

I got max value from this query, but how to use this in visualizations buckets ?

GET logstash-report-2017.10.13/\_search  
{  
"aggs" : {  
"max\_id" : { "max" : { "field" : "build\_number" } }  
}  
}

Right now there's no way to create a query that uses the results of a previous request in an automated fashion. Those sorts of multi-stage queries are something we'd like to explore in the future.

If you just want to create a bucket for the max build number that you can then add sub-buckets to, you might be able to hack this together.

Create a new vis with a "Max build\_number" metric on the y-axis. Create a "Split Chart" bucket with a terms agg of size 1 on the build\_number field, ordered by the max metric. Now add whatever additional metrics and buckets you want. I think that's about as close as you'll get currently. See example below.
