Chaincode queries with couchDB #fabric-chaincode

Hi,

I followed the doc (https://hyperledger-fabric.readthedocs.io/en/latest/couchdb_as_state_database.html ) to create index as below:

{

    "index": {

        "fields": ["ownerName", "paymentAmountDue"]

    },

    "ddoc": "ownerIndexDoc",

    "name": "ownerIndex",

    "type": "json"

}


Then I use this index to query by using:

{"selector":{"ownerName":"Joe","paymentAmountDue": "0"}}
 
It works and the query returns all transactions having ownerName="Joe" and paymentAmountDue = 0.

Now I want to  query all transactions having ownerName="Joe" and paymentAmountDue <> 0. How can I achieve this?

Thx in advance.
