You're almost here, you're just missing a few things:
PUT /test
{
"mappings": {
"type_name": { <--- add the type name
"properties": { <--- enclose all field definitions in "properties"
"field1": {
"type": "integer"
},
"field2": {
"type": "integer"
},
"field3": {
"type": "string",
"index": "not_analyzed"
},
"field4,": {
"type": "string",
"analyzer": "autocomplete",
"search_analyzer": "standard"
}
}
}
},
"settings": {
...
}
}
UPDATE
If your index already exists, you can also modify your mappings like this:
PUT test/_mapping/type_name
{
"properties": { <--- enclose all field definitions in "properties"
"field1": {
"type": "integer"
},
"field2": {
"type": "integer"
},
"field3": {
"type": "string",
"index": "not_analyzed"
},
"field4,": {
"type": "string",
"analyzer": "autocomplete",
"search_analyzer": "standard"
}
}
}
UPDATE:
As of ES 7, mapping types have been removed. You can read more details here
