What is the difference between sqto and sfto.  
I assume sqto is search query operation per shard and sfto is fetching source of the document once we have document ids from search query operations. I cannot find anything in the reference to confirm my assumptions.

Thanks

[https://www.elastic.co/guide/en/elasticsearch/reference/6.2/cat-nodes.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/cat-nodes.html) has these.

searchFetchTotal = Number of fetch operations  
searchQueryTotal = Number of query operations

Hi warkolm  
I have read the links but could not comprehend if

searchFetchTotal = Number of fetch operation  
Does it mean operation per shard or per segment on the node

searchQueryTotal = Number of query operations  
Does it mean source of a document is fetched from the node

Thank you

If you are using `_cat/nodes`, it gives you the number of queries per node and the number of fetches per node.
