In ES 5.0, is there a way to treat the new `keyword` field in case-insensitive manner?

Not yet. See [https://github.com/elastic/elasticsearch/issues/18064](https://github.com/elastic/elasticsearch/issues/18064)

That's too bad ☹
The ticket does not seem to active really. Do you have an idea when will it be available?

I believe it is planned for 5.1 but @jpountz might tell you more. (I know he is very active on this feature).

I know it doesn't look active since most work is happening in Lucene at the moment, but this is a feature that we know many users are interested in.

Thanks you guys. Looking forward to see it working soon.

So what is the suggested workaround right now? Should using a text field with custom analyzer and enabling fielddata perform ok?

We used custom analyzer as workaround:
```
"analyzer": {
"lowercase_keyword": {
"filter": "lowercase",
"type": "custom",
"tokenizer": "keyword"
}
}
```

Doesn't that give a field data error?

I've added a custom analyser:
> "analyzer": {
> "folding": {
> "tokenizer": "standard",
> "filter": ["lowercase", "asciifolding"]
> }
> },
I've also added a dynamic template in order to set the datatype of my fields. I've the following for keyword.
> {
> "string\_as\_keyword": {
> "match\_mapping\_type": "string",
> "match": "\*\_k",
> "mapping": {
> "type": "keyword",
> "analyzer": "folding"
> }
> }
> },
Is that correct? How can I query my data? I've found a lot of information about older versions but not for 5.0.

You [can't add an analyzer to the keyword type](https://github.com/elastic/elasticsearch/issues/18064).
In 5.2.0 you will be able to define a `normalizer`:

But if it's about search and not aggregations, then use a type `text` instead. It supports an analyzer.
