  +Check the CouchDB interface at [`http://localhost:5984/_utils/`](http://localhost:5984/_utils/) to see new records added under the database utilityemissionchannel_emissionscontract. More complex queries can be run with Mango at [`http://localhost:5984/_utils/#database/utilityemissionchannel_emissionscontract/_find`](http://localhost:5984/_utils/#database/utilityemissionchannel_emissionscontract/_find) (see [here](https://docs.couchdb.org/en/stable/intro/tour.html?highlight=gte#running-a-mango-query) for more information on running Mango queries).

  +To search for utility emissions, run the Mango query:

  +```json

  + "class": {
  + "$eq": "org.hyperledger.blockchain-carbon-accounting.utilityemissionsfactoritem"
  + }
  + }
