| key | 用于获取值的密钥。 |
| value | 要存储在索引中的字符串值。 |
| documentIndex | 找到已编制索引的值的文档。 |
| saveKeyword | 表示是否将此密钥存储在该索引的关键字注册表中。请参阅 SearchIndexer.GetKeywords. |
| exact | 如果为真，该索引将为此词存储一个完全匹配的条目。 |
| score | 该词的相关性得分。 |
| name | 用于获取值的密钥。 |
| minVariations | 为值计算的最小变化数。不能高于单词的长度。 |
| maxVariations | 为值计算的最大变化数。不能高于单词的长度。 |
向索引添加属性值。属性使用密钥和字符串值指定。该值将存储有多种变化形式。
