 <<mapping-boost,`boost`>>::
 
- Mapping field-level query time boosting. Accepts a floating point number, defaults
- to `1.0`.
+ 映射字段级别查询时间提升。接受一个浮点数，默认为 `1.0` 。
 
 <<doc-values,`doc_values`>>::
 
- Should the field be stored on disk in a column-stride fashion, so that it
- can later be used for sorting, aggregations, or scripting? Accepts `true`
- (default) or `false`.
+ 字段是否应该以多列的方式存储在磁盘上，以便以后可以将其用于排序，聚合或脚本？接受 `true` （默认）或 `false` 。
 
 <<mapping-index,`index`>>::
 
- Should the field be searchable? Accepts `true` (default) and `false`.
+ 字段是否可搜索？接受 `true` （默认）或 `false` 。
 
 <<null-value,`null_value`>>::
 
- Accepts any of the true or false values listed above. The value is
- substituted for any explicit `null` values. Defaults to `null`, which
- means the field is treated as missing.
+ 接受上面列出的任何真值或假值。该值被替换为任何显式空值。默认为 `null` ，意味着该字段被视为缺失。
 
 <<mapping-store,`store`>>::
 
- Whether the field value should be stored and retrievable separately from
- the <<mapping-source-field,`_source`>> field. Accepts `true` or `false`
- (default).
+ 字段值是否应与 <<mapping-source-field,`_source`>> 字段分开存储和检索。接受 `true` 或 `false` （默认）。
