How to cancel/stop current long running search request in Elasticsearch?

Elastic Stack Elasticsearch
1

My index has almost 50 million records in it and sometime It will take to much time to execute with a search request
So can we cancel current running search request?

{
query:{
search request:
{
filter criteria:{
//taking long time to execute
}
}
}
}

so how we can cancel particular request executing in ES server?
