Hello All,

I want to create this analyzer using JAVA API of elasticsearch. Can any one help me? I tried to add tokenizer and filter at a same time, but could not do this.

```
"analysis": {
  "analyzer": {
      "case_insensitive_sort": {
         "tokenizer": "keyword",
         "filter": ["lowercase"]
       }
    }
  }

```

I get the reference to this.  
[https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-analyze.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-analyze.html)

Till 7.2 I can able to create analyzer using .filter() and .tokenizer() method. Can anyone help on that part?

Hey,

the `AnalyzeRequest` has a couple of custom `buildCustomAnalyzer` methods where you can specify token filters and char filters settings. There is an example in the analyze documentation for the high level rest client at [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-high-analyze.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-high-analyze.html) using maps.
