Finding Your Data with Views > Find One > Might need to explain encoding for CURL

Say we know the date of a blog post. To find a single document, we would use /blog/_design/docs/_view/by_date?key="2009/01/30 18:04:11" to get the “Biking” blog post. Remember that you can place whatever you like in the key parameter to the emit() function.

Again, just following along. I can't make it work to get just one document. Here's my successful request to get all docs:

$ curl http://127.0.0.1:5984/basic/_design/blog/_view/by_date
{"total_rows":3,"offset":0,"rows":[
{"id":"hello-world","key":"2009/01/15 15:52:20","value":"Hello World"},
{"id":"biking","key":"2009/01/30 18:04:11","value":"Biking"},
{"id":"bought-a-cat","key":"2009/02/17 21:13:39","value":"Bought a Cat"}
]}

And here's me failing to grab a single doc by key:

$ curl http://127.0.0.1:5984/basic/_design/blog/_view/by_date?key="2009/01/15 15:52:20"

$ curl http://127.0.0.1:5984/basic/_design/blog/_view/by_date?key="2009%2F01%2F15 15:52:20"
{"error":"bad_request","reason":"invalid_json"}

$ curl http://127.0.0.1:5984/basic/_design/blog/_view/by_date?key="2009%2F01%2F15%2015%3A52%3A20"
{"error":"bad_request","reason":"invalid_json"}

$ curl -v http://127.0.0.1:5984/basic/_design/blog/_view/by_date?key="2009/01/15 15:52:20"

Not sure if this is an issue with the documentation, or if I'm just being an idiot...

PS - I'm still using the "basic" database from an earlier chapter. But I'd still expect this to work as I can still get all the docs for that view....

Aha, I forgot to escape the quotations, this worked fine:

curl http://127.0.0.1:5984/basic/_design/blog/_view/by_date?key=?key=%222009/01/15%2015:52:20%22

I'll leave this issue open in case it needs documenting.
