Hello,

I am new to Elastic.

I am getting the following error while uploading the ES index template.

```
{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Mapping definition for [path] has unsupported parameters:  
[field : {keyword={ignore_above=256, type=keyword}}]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [_doc]: 
Mapping definition for [path] has unsupported parameters: [field : {keyword={ignore_above=256, type=keyword}}]","caused_by":
{"type":"mapper_parsing_exception","reason":"Mapping definition for [path] has unsupported parameters: 
 [field : {keyword={ignore_above=256, type=keyword}}]"}},"status":400}

```

This is my index

```
{
	"mappings": {
		"_doc": {
			"properties": {
				"offerId": {
					"type": "text",
					"fields": {
						"keyword": {
							"type": "keyword",
							"ignore_above": 256
						}
					}
				},
				"offerDetail": {
                                        "type"= "nested",
					"properties": {
						 "dataStatus" : {
						 	"properties": {
						 		"value": {
						 			"type": "text",
						 			"field": {
						 				"keyword": {
						 					"type": "keyword",
						 					"ignore_above": 256
						 				}
						 			}
						 		},
						 		"content": {
						 			"properties": {
						 				"key": {
						 					"type": "text",
						 					"field": {
						 						"keyword": {
						 							"type": "keyword",
						 							"ignore_above": 256
						 						}
						 					}	
						 				}
						 			}
						 		}
						 	}
				 		},
				 		"images": {
				 			"properties": {
				 				"path": {
				 					"type": "text",
				 					"field": {
				 						"keyword": {
				 							"type": "keyword",
				 							"ignore_above": 256
				 						}
				 					}
				 				},
				 			}
				 		},
				 		"annualPrice": {
				 			"properties": {
				 				"cutPriceExcludingVat": {
				 					"type": "long"
				 				},
								"monthlyExcludingVat": {
									"type": "long"
								},
								"quotationId": {
				 					"type": "text",
				 					"field": {
				 						"keyword": {
				 							"type": "keyword",
				 							"ignore_above": 256
				 						}
				 					}
								}
				 				
				 			}
				 		}
				 	}
				}
			}
		}
	}
}

```

I get this error for all the attributes that the are multi field (text with field keyword" What I tried to do is to change the type of path to "keyword" and not multiple fields.

```
					 				"path": {
					 					"type": "keyword"	
					 				}

```

And that pass. But I need to understand why I can go with the multi fields ??

The issue here is because multi-field should be declared with `fields` and not `field`. The definition for property `offerId` is correct but all the others are wrong.
