Hi,

I am parsing Elasticsearch explain output. I am trying to find out how deep  
can be be the first relevant description as part of value, description,  
details combination. I am trying to parse descriptions that have either  
"weight" or "CustomScore".

As I could not find a Json parser that has XPath like functionality in  
finding sibling nodes (say I found a description node because matched on  
string "weight(" then I want to collect the "value" which is sibling node)  
I am relying on recursion. I have seen a description with "weight" or  
"CustomScore" to be 5 levels deep, from the first value, description,  
details combination. this is ok by me. I was wondering if it ever goes to  
higher magnitutes say 10, 20 or 30.

Regards,

Suhaas
