                    "tokenizer" : "standard",
                    "filter" : ["standard", "lowercase", "my_snow"]
               },

You could change the dbl_metaphone and shingle analysers
indent preformatted text by 4 spaces
{
"settings": {
"index.mapping.total_fields.limit": 2000,
"analysis": {
"analyzer": {
"default": {
"type": "custom",
"tokenizer": "standard",
"filter": ["lowercase","custom_edge_ngram"]
},
"dbl_metaphone":{
"type": "custom",
"tokenizer": "standard",
"filter": ["dbl_metaphone"]
},
"shingle":{
"type": "custom",
"tokenizer": "standard",
"filter": ["shingle-filter"]
}
},
"filter": {
"custom_edge_ngram": {
"type": "edge_ngram",
"min_gram": 2,
"max_gram": 10
},
"dbl_metaphone": {
"type": "phonetic",
"encoder": "double_metaphone"
},
"shingle-filter": {
"max_shingle_size": "5",
"min_shingle_size": "2",
"output_unigrams": "false",
"type": "shingle"
}
}}}},

"mappings": {
"_doc": {
--------------------------
"content": {
"type": "text"
"index_analyzer": "default",
"search_analyzer" : "standard",
"fields:{
"phonetic":{
"type":"text",
"analyzer":"dbl_metaphone"
},
"shingle":{
"type":"text",
"analyzer":"shingle"
}
}
},
indent preformatted text by 4 spaces
