I have a string I'd like to index as keyword type but with a special comma analyzer:
For example:
`"San Francisco, Boston, New York"`
should be both indexed and aggregatable at the same time so that I can split it up by buckets. In pre 5.0.0 the following worked:
Index settings:
```
{
'settings': {
'analysis': {
'tokenizer': {
'comma': {
'type': 'pattern',
'pattern': ','
}
},
'analyzer': {
'comma': {
'type': 'custom',
'tokenizer': 'comma'
}
}
},
},
}
```
with the following mapping:
```
{
'city': {
'type': 'string',
'analyzer': 'comma'
},
}
```
Now in 5.3.0 and above the `analyzer` is no longer a valid property for the `keyword` type, and my undestanding is that I want a `keyword` here. How do I specify an aggregatable, indexed, searchable text type with custom analyser?

if you specify an analyzer that produces more than one token you have to use `text` type since it's not a keyword. if you wanna use a `normalizer` you can use a [keyword](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/keyword.html) type but then you need to split your tokens in the client and send a list (`"San Francisco, Boston, New York" -> ["San Francisco", "Boston", "New York"]`) Since keywords don't allow tokenization. If you use `text` as a type you can't use docvalues anymore and for aggregations all terms will be loaded into memory.
