# elastic search

## ElasticSearch xây dựng như 1 bộ api có sẵn cung cấp đầy đủ các thông tin để sử dụng

Đầu tiên table trong elastic được gọi là index > khi tạo index thì ta phải mapping kiểu dữ liệu để elastic search có thể dựa vào đó để index cho quá trình search

```
curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
  "mappings": {
    "properties": {
      "foo_field": {
        "type": "text"
      }
    }
  }
}'
```

Khi update lại mapping

In later Elasticsearch versions (7.x), types were removed.

```
curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
  "properties": {
    "new_geo_field": {
      "type": "geo_point"
    }
  }
}'
```
