Sorry, your question was clear, I don't use search parameters in my app and got confused, I just check it and it's actually `location.search` that return a string `?genre=mystery'. The props passed to the component by `route` are not yet documented, this is what I gathered:

  "path": "/:genre",
  "computedMatch": 
    "path": "/:genre",
    "url": "/foo",
    "isExact": true,
    "params": 
      "genre": "foo"
  "length": 7,
  "action": "POP",
  "location":
    "pathname": "/foo",
    "search": "?genre=mystery",
    "hash": ""
  "match": 
    "path": "/:genre",
    "url": "/foo",
    "isExact": true,
    "params": 
      "genre": "foo"
