Unsecret Agent not returning results for connections to UMLS identifiers for vomiting/nausea about medikanren HOT 1 CLOSED

Hi @MarkDWilliams , I tried your query and noticed you were giving the type "ChemicalSubstance" to "UMLS:C0520909", but that curie is actually the disease/phenotype "Postoperative Nausea and Vomiting".

Also, we don't currently support concept subtyping, so "named_thing" is going to miss possible results. Here is a modified version of your query (changing only the type of each node) that gives back some answers:

{"message":{
  
  "query_graph": {
    "nodes": [
      {
        "id": "n0",
        "set": false,
        "curie":"UMLS:C0520909"
      },
      {
        "id": "n1",
        "type": "disease",
        "set": false
      }
    ],
    "edges": [
      {
        "id": "e0",
        "source_id": "n1",
        "target_id": "n0"
      }
    ]
  }
}}
