JEDIS, Query nested tables, how?

I have JSON structure in REDIS that looks something like:

{ "name": "value" "subtable": { "sub1":{ "subtime": 123456 } "sub2":{ "subtime": 999999 } } } 

I tried to build me schema like:

addNumberField($.subtable[*].subtime,1).as("subtime") 

but off course this is for an array, not a hash.

Can someone point me to documentation of doing this thru a hash?

My query looks like:

Query().addFilter(new Query.NumericFilter("subtime",999998,999999) 

TIA

Tried many things, and got pretty lost.
