how can we implement ngram_anlyzer without affecting the phrase_search

[Anand kumar]

Hi,

I want to search the ngram analyzed data without being affected the results 
of phrase search.

If I used the ngram analyzer, it affects the phrase search results. For 
instance, I'm querying for the string "phrase query", it would display the 
results for exact match, instead it outputs match for "phrase" and "query". 
Here are the settings I've been using, what should be done to get the 
desired result.


"settings" : {
           "index": {
    "analysis" : {
                "analyzer" : {
                    "my_ngram_analyzer" : {
                        "tokenizer" : ["my_ngram_tokenizer", "whitespace"],
"filter" : "lowercase"
                    }
                },
                "tokenizer" : {
                    "my_ngram_tokenizer" : {
                        "type" : "nGram",
                        "min_gram" : "3",
                        "max_gram" : "20",
                        "token_chars": [ "letter", "digit" ]
                    }
                }
            }
     }

}
