Hi

I am using category, which is a hierarchical field represented as `level1>level2>level3>level4`  
I want to make a query that can apply filter on `level2` or `level3` individually. So, I am using `simple_pattern_split` tokenizer and mapping looks like this

```auto
"category_id": {
  "type": "text",
  "analyzer": "category_id_analyzer",
  "search_analyzer": "category_id_analyzer"
},

```

analyzer

```auto
"category_id_analyzer": {
  "tokenizer": "custom_tokenizer"
}

```

tokenizer

```auto
"custom_tokenizer": {
  "type": "simple_pattern_split",
  "pattern": ">"
}

```

But, I also want to perform aggregations on each individual category which can only be done if `type: keyword` but it gives error  
`Mapping definition for [category_id] has unsupported parameters: [search_analyzer : category_id_analyzer] [analyzer : category_id_analyzer]`

Can someone suggest what should be done ?  
Thanks
