Elasticsearch Map case insensitive to not_analyzed documents

Question

I have a type with following mapping

PUT /testindex {     "mappings" : {         "products" : {             "properties" : {                 "category_name" : {                     "type" : "string",                     "index" : "not_analyzed"                  }             }         }     }  } 

I wanted to search for an exact word.Thats why i set this as not_analyzed. But the problem is i want to search that with lower case or upper case[case insensitive].

I searched for it and found a way to set case insensitive.

curl -XPOST localhost:9200/testindex -d '{   "mappings" : {     "products" : {       "properties" : {                 "category_name":{"type": "string", "index": "analyzed", "analyzer":"lowercase_keyword"}       }     }   } }' 

Is there any way to do these two mappings to same field.?

Thanks..

I think this example meets your needs:

$ curl -XPUT localhost:9200/testindex/ -d ' {   "settings":{      "index":{         "analysis":{            "analyzer":{               "analyzer_keyword":{                  "tokenizer":"keyword",                  "filter":"lowercase"               }            }         }      }   },   "mappings":{      "test":{         "properties":{            "title":{               "analyzer":"analyzer_keyword",               "type":"string"            }         }      }   } }' 

taken from here: How to setup a tokenizer in elasticsearch

it uses both the keyword tokenizer and the lowercase filter on a string field which I believe does what you want.
