ElasticSearch: analyzer on field must be set when search_analyzer is set - elasticsearch

Question

I have read about previous version of ES (< 2) where the "token_analyzer" key needs to be changed to "analyzer". But no matter what I do I am still getting this error:
"type": "mapper_parsing_exception",
"reason": "analyzer on field [email] must be set when search_analyzer is set"
Here is what I am passing into ES via a PUT function when I get the error:
{
"settings": {
"analysis": {
"analyzer": {
"my_email_analyzer": {
"type": "custom",
"tokenizer": "uax_url_email",
"filter": ["lowercase", "stop"]
}
}
}
},
"mappings" : {
"uuser": {
"properties": {
"email": {
"type": "text",
"search_analyzer": "my_email_analyzer",
"fields": {
"email": {
"type": "text",
"analyzer": "my_email_analyzer"
}
}
},
"facebookId": {
"type": "text"
},
"name": {
"type": "text"
},
"profileImageUrl": {
"type": "text"
},
"signupDate": {
"type": "date"
},
"username": {
"type": "text"
}
,
"phoneNumber": {
"type": "text"
}
}
}
}
}
Any ideas what is wrong?

Answer 1

Because you have specified a search_analyzer for the field, you also have to specify the analyzer to be used at indexing time. For example, add this line under where you specify the search_analyzer:
"analyzer": "standard",
To give you this:
{
"settings": {
"analysis": {
"analyzer": {
"my_email_analyzer": {
"type": "custom",
"tokenizer": "uax_url_email",
"filter": ["lowercase", "stop"]
}
}
}
},
"mappings" : {
"uuser": {
"properties": {
"email": {
"type": "text",
"search_analyzer": "my_email_analyzer",
"analyzer": "standard",
"fields": {
"email": {
"type": "text",
"analyzer": "my_email_analyzer"
}
}
},
"facebookId": {
"type": "text"
},
"name": {
"type": "text"
},
"profileImageUrl": {
"type": "text"
},
"signupDate": {
"type": "date"
},
"username": {
"type": "text"
}
,
"phoneNumber": {
"type": "text"
}
}
}
}
}
