在字段中搜索（Search in fields）

Search specific fields rather than the default. Terms, phrases, etc. can all be preceded by a field. If not the default field TEXT is used.
搜索特定字段而不是默认字段。术语、短语等都可以在前面指定查询的字段名。如果没有指定，则使用默认字段TEXT。

field:term
field:"phrase"
=field:exact
~field:expand

Fields fall into three types: property fields, special fields, and fields for data types.
字段分为三种类型：属性字段、特殊字段和数据类型字段。

Property fields evaluate the search term against a particular property, special fields are described in the following table, and data type fields evaluate the search term against all properties of the given type.
属性字段根据特定属性计算搜索项，下表中描述了特定字段，数据类型字段根据给定类型的所有属性计算搜索项。
