Hey, i want to search my records case insensitive. I have the following mapping in my field:

```
"name": {
                    "type": "string",
                    "analyzer": "lowercase_analyzer"
                  },

```

Where lowercase\_analyzer is:

```
"settings": {
    "analysis": {
      "analyzer": {
        "lowercase_analyzer": {
          "type": "custom",
          "tokenizer": "keyword",
          "filter": [
            "lowercase"
          ]
        }
      }
    }
  }

```

If i now search on my name with anything else as lowercase, it does not find my records.

Is there anyway to have a case insensitive mapping?

yes, you have to change your tokenizer from keyword to whitespace or standard, you can also set your language rules [https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-lang-analyzer.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-lang-analyzer.html) . keyword tokenizer, as described in documentation [https://www.elastic.co/guide/en/elasticsearch/reference/5.0//analysis-keyword-tokenizer.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.0//analysis-keyword-tokenizer.html), take all the terms in that field and make them a single token, a keyword. This setting is useful when you index fields with few but significant words(es. New York and New Mexico as a single token, a code like ak234, as a single token,etc.

Thanks for the reply.

The problem is that i still need to take all the terms and make them a single token. but i also need it to be case insensitive. is that possible?
