Groovy 用于批量/更新文档而不获取文档的复杂脚本

对于我的项目，我有以下ES映射表示：

- BOOK
    - label: String,
    - active: Boolean
    - total_term_occ: Long

- TERMS
    - label: String,
    - ngram: Byte,
    - tot_occurrences: Long,
    - books [{
        - id: String,
        - label: String,
        - occurrences: Long,
        - tfidf: Double
    }]

对于每个新学期（例如：“ES rocks”），我想：

- Update the total occurrence in the "TERMS" doc
OR 
- Create the new term if not exists
AND (if term already exists)
- BOOK :
    - Create a new object if the book does not already exist with "occurrences" to 0 and "tfidf" to NULL
    OR
    - Update the "occurrences" field if the book exists (with a loop ?!)

我想批量请求“更新->脚本->升级”，但在更新之前不获取文档

您认为选择映射是否可行？我找不到好的解决办法
