Hello,

I have encountered an issue in Logstash. Currently I am using LS, 2.0.0.

Now, in my mapping. Previously I have a field:

```
"content" : {
                   "type" : "string",
                   "index" : "not_analyzed"
                 },

```

I output data there that will exceed the container of 32,766 bytes.

It throws the error of:

> "reason" =\> "Document contains at least 1 immense term in field="content" (whose UTF8..."

I found this in stackoverflow: [elasticsearch - UTF8 encoding is longer than the max length 32766 - Stack Overflow](http://stackoverflow.com/questions/24019868/utf8-encoding-is-longer-than-the-max-length-32766)

So to make this work, I have to do this:

```
        "content" : {
                           "type" : "string",
                           "index" : "no"
                         },

```

It fixes the issue. Based on that overflow thread, it says that it still makes the field of content not "filterable" or searchable.

I wanted to discuss on why did it fix the issue? I found no source material (or I did not see it) in elasticsearch doucmentation. Could anyone explain to me the pro's of using "index" : "no" against "index" : "not\_analyzed"?

I plan to use the "index" : "no", in my mapping so that I can fix the issue. I just want to know why it worked and what are its pros and cons.

Thanks,

---
