elasticsearchHow do I create an Elasticsearch mapping?
To create an Elasticsearch mapping, you need to define the structure of your data in a JSON document. This document is then sent to the Elasticsearch server via an API call.
The following example code demonstrates how to create a mapping for an index called my_index
:
PUT my_index
{
"mappings": {
"properties": {
"user": {
"type": "keyword"
},
"message": {
"type": "text"
}
}
}
}
The output of the above code will be a 200 OK
response.
The code consists of the following parts:
PUT my_index
: This is the API call to create the index.mappings
: This is the key that holds the mapping definition.properties
: This is the key that holds the field definitions.user
andmessage
: These are the field names.type
: This is the data type of the field.
For more information on creating mappings in Elasticsearch, please refer to the official documentation.
