Hi,

I am following this:

[https://www.elastic.co/guide/en/elasticsearch/guide/current/\_index\_time\_search\_as\_you\_type.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_index_time_search_as_you_type.html)

My settings look like this:

```auto
{
  "parts": {
    "settings": {
      "index": {
        "creation_date": "1455184604925",
        "analysis": {
          "filter": {
            "autocomplete_filter": {
              "type": "edge_ngram",
              "min_gram": "1",
              "max_gram": "20"
            }
          },
          "analyzer": {
            "autocomplete": {
              "filter": [
                "lowercase",
                "autocomplete_filter"
              ],
              "type": "custom",
              "tokenizer": "standard"
            }
          }
        },
        "number_of_shards": "1",
        "number_of_replicas": "1",
        "uuid": "BnzMGfSBRAWq5Wnnd1KJyg",
        "version": {
          "created": "2010199"
        }
      }
    }
  }
}

```

but when I do:

curl -XPOST '[http://blahblah:9200/\_analyze?analyzer=autocomplete](http://blahblah:9200/_analyze?analyzer=autocomplete)' -d 'bel'

my terminal just seems to hang

But this works:

curl -XPOST '[http://blahblah:9200/\_analyze?analyzer=standard](http://blahblah:9200/_analyze?analyzer=standard)' -d 'bel'

{"tokens":[{"token":"bel","start\_offset":0,"end\_offset":3,"type":"","position":0}]}

I can see this is the log:

```auto

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
        at java.lang.Thread.run(Thread.java:745)

```

Looks like it could be this:

I will get my documents indexed and see what happens.

Seems to be working OK.

I needed this as well:
