[英]Exclude fields from being indexed by Elasticsearch via CouchDB-River
[英]How to exclude fields from being indexed in ElasticSearch?
我正在嘗試利用 ElasticSearch 來存儲大量數據。 大多數數據都是可搜索的,但是,有一些字段將在那里,以便數據被存儲並根據請求返回。
這是我的映射

fields
和price_changes
屬性在用戶想要閱讀該信息的情況下存在。 但該信息不應該是可搜索或索引的。 這些fields
包含大量key-value
對,而price_changes
字段包含多個相同類型的對象。
目前,當我嘗試批量創建記錄時,我得到Limit of total fields [1000] has been exceeded
錯誤。 我猜這個錯誤正在發生,因為fields
集合中的每個鍵值對都被認為是 elasticsearch 中的一個字段。
如何將fields
和price_changes
object 存儲為不可搜索的數據,而不是將其編入索引或計入字段計數?
您可以在字段級別使用 enabled 屬性來存儲字段而不對其進行索引。 在這里閱讀https://www.elastic.co/guide/en/elasticsearch/reference/current/enabled.html
"price_changes": {
"type": "object",
"enabled": false
}
注意:您是否能夠使用您在問題中提供的映射創建索引? 它在“類型”字段中給了我語法錯誤(重復鍵)。 我認為您缺少“城市”字段的右括號。
