Hello,

I want to use the whitespace tokenizer and be able to have my search be case insensitive.

However, I am unable to do case insensitive searches when using the whitespace tokenizer. This is what my settings look like ...

"analysis": {  
"analyzer": {  
"default": {  
"filter": "lowercase",  
"type": "whitespace",  
"tokenizer": "whitespace"  
}  
}  
}

What am I doing wrong? What should I do to fix it?

Thanks.

In your analyzer config `type` should be set to `custom` and you should use a different name than `default` (`default` is already an built-in analyzer):

```auto
“analysis”: {
   “analyzer”: {
      “my_analyzer”: {
         "type": "custom",
         “tokenizer”: “whitespace”,
         “filter”: “lowercase”
      }
  }
}

```

Then in the mapping you can set the `analyzer` option to `my_analyzer` on text fields.

Also you don't need an custom analyzer for this, I think just using the built-in `simple` analyzer does the same thing. The only thing you need to do is set the `analyzer` option to `simple` on a text field.
