A way to check for existence of an index or river?

[victor73]

Is there a way to check for the existence of a particular index? I found the indexExists() method, however it doesn't seem to be documented or to work as expected. An index name that definitely exists according to the output of a curl call to /_status and /index_name/_status seems to return false when passed to indexExists():

client.indexExists(indexName, function(err, exists) {
    if (err) {
        throw err;
    }

    if (exists) {
        console.log("Exists");
    } else {
        console.log("Doesn't exist");
    }
});

Client#indexExists() is documented here: https://github.com/rgrove/node-elastical/blob/master/lib/client.js#L339-352

It calls the static Index.exists() method, which is documented here: https://github.com/rgrove/node-elastical/blob/master/lib/index.js#L256-279

The unit tests for this method pass, so it seems to be working. Can you give me more details about your ElasticSearch version, or possibly write a failing unit test that demonstrates the problem in a reproducible way?

The elasticsearch version is 18.6:

$ curl -X GET server:9200 | json version.number
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   361  100   361    0     0   152k      0 --:--:-- --:--:-- --:--:--     0
{
  "version": {
    "number": "0.18.6"
  }
}

I'll try to write a test to demonstrate...

Ugh. Seems like I was supplying "http://" at the beginning of the value for the server. Once I remove the "http://" it works fine. My mistake. However, I think some sort of exception should have been thrown in this case...

Hmm, yeah, Index.exists() ought to pass along the error from Request if there is one, and there should be one in that case. That's a valid bug, thanks!
