Only for the records, I will describe here what I did to solve this
problem. This is specific for those who are using python/requests and Solr
json facet api.
I would like to ask another question regarding json facet.

I was not aware how to POST data with same key on Python. It was due to my
unfamiliarity of the details of the protocol and the libs.
In python/requests library, one way to send data over POST is to use a
dictionary, that has a unique key by design.
But I realise that I can send data as a list of tuples like this:
[('q','*:*'), ('fl','*'), ('json.facet',facet_fields), ('fq', 'fq_1'),
'fq', 'fq_2'), 'fq', 'fq_3')]
The facet layer of my system now works entirely using solr json facet api
over http post.
