I have a mappings like this
{
"mappings": {
"telephones": {
"properties": {
"test": {
"type": "string",
"index": "no",
"include_in_all": false
},
"rawTelephone": {
"type": "string",
"index": "no",
"include_in_all": false
},
"telephone": {
"type": "string",
"copy_to": ["phonekey"],
"index": "not_analyzed",
"include_in_all": false
},
"type": {
"type": "string",
"index": "not_analyzed",
"include_in_all": false
},
"phonekey": {
"type": "string"
}
}
}
}
}
Now the values of telephone is copied to "phone key" from the results of phone key the last 7 digit should only analyzed
how to analyze it?
