Hi,

I was wondering what is the best way to extract a csv with the various  
terms of some fields alongside with the corresponding counts? For example  
create a csv as follows:

productId, product, category, city, hour, products\_count,

> selled\_products\_count

Will cat API be useful in this case? Or I have to pass from multiple  
aggregation calls to construct this information?

Thanks  
Thomas

You'll probably need to parse the JSON query results in your programming  
language to constuct a CSV result yourself. No the CAT API has a different  
purpose - it is used to display columnar views of cluster/index/node info  
and statistics - not query results.
