MapperParsingException when creating mapping for elasticsearch index - elasticsearch

Question

Using sense, I'm trying to create a mapping for an index with three properties. When i try to create it i get the following response
{
"error": "MapperParsingException[Root type mapping not empty after parsing! Remaining fields: [mappings : {gram={properties={gram={type=string, fields={gram_bm25={type=string, similarity=BM25}, gram_lmd={type=string}}}, sentiment={type=string, index=not_analyzed}, word={type=string, index=not_analyzed}}}}]]",
"status": 400
}
This is what i have in the sense console
PUT /pos/_mapping/gram
{
"mappings": {
"gram": {
"properties": {
"gram": {
"type": "string",
"fields": {
"gram_bm25": {
"type": "string", "similarity": "BM25"
},
"gram_lmd": {
"type": "string"
}
}
},
"sentiment": {
"type": "string", "index": "not_analyzed"
},
"word": {
"type": "string", "index": "not_analyzed"
}
}
}
}
}
The name of the index is 'pos' and I call the type 'gram'.
I have created the index with the same name.
I have validated the json using http://jsonlint.com/
I tried using XPUT in the console and i got the 'aknowleged' response, but the mapping is still {} when i request it in sense.
this question does not solve my problem. I always use the same name everywhere.
Any suggestions?
Thanks!

You just have the API syntax wrong. You've combined two different methods, basically.
Either create your index, then apply a mapping:
DELETE /pos
PUT /pos
PUT /pos/gram/_mapping
{
"gram": {
"properties": {
"gram": {
"type": "string",
"fields": {
"gram_bm25": {
"type": "string",
"similarity": "BM25"
},
"gram_lmd": {
"type": "string"
}
}
},
"sentiment": {
"type": "string",
"index": "not_analyzed"
},
"word": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
Or do it all at once when you create the index:
DELETE /pos
PUT /pos
{
"mappings": {
"gram": {
"properties": {
"gram": {
"type": "string",
"fields": {
"gram_bm25": {
"type": "string",
"similarity": "BM25"
},
"gram_lmd": {
"type": "string"
}
}
},
"sentiment": {
"type": "string",
"index": "not_analyzed"
},
"word": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
Here's the code I used:
