Elasticsearch keyword tokenizer doesn't work with phonetic analyzer - elasticsearch

Question

I want to add a custom phonetic analyzer, also I don't want to analyze my given string. Suppose, I have two string,
KAMRUL ISLAM
KAMRAL ISLAM
I don't want to get any result with a query string KAMRUL but want both two as a result with query string KAMRUL ISLAM.
For this, I have take a custom phonetic analyzer with a keyword tokenizer.
Index Settings :
PUT /my_index
{
"settings": {
"analysis": {
"filter": {
"dbl_metaphone": {
"tokenizer": "keyword",
"type": "phonetic",
"encoder": "double_metaphone"
}
},
"analyzer": {
"dbl_metaphone": {
"tokenizer": "keyword",
"filter": "dbl_metaphone"
}
}
}
}
}
Type Mappings:
PUT /my_index/_mapping/my_type
{
"properties": {
"name": {
"type": "string",
"analyzer": "dbl_metaphone"
}
}
}
I have inserted data with :
PUT /my_index/my_type/5
{
"name": "KAMRUL ISLAM"
}
And My query String:
GET /my_index/my_type/_search
{
"query": {
"match": {
"name": {
"query": "KAMRAL"
}
}
}
}
Unfortunately I am given both two string. I am using ES-1.7.1. Is there any way to solve this ?
Additionally, While I have run
curl -XGET 'localhost:9200/my_index/_analyze?analyzer=dbl_metaphone' -d 'KAMRUL ISLAM'
I got the result:
{
"tokens": [
{
"token": "KMRL",
"start_offset": 0,
"end_offset": 12,
"type": "word",
"position": 1
}
]
}
And While running :
curl -XGET 'localhost:9200/my_index/_analyze?analyzer=dbl_metaphone' -d 'KAMRAL'
I have got:
{
"tokens": [
{
"token": "KMRL",
"start_offset": 0,
"end_offset": 6,
"type": "word",
"position": 1
}
]
}
