将同义词库添加到索引中

以下过程说明如何将包含同义词的同义词库文件添加到索引中。要了解更新后的同义词库文件的效果，最多可能需要 30 分钟。有关同义词库文件的更多信息，请参阅创建同义词库文件。

Console

添加同义词库

1. 在左侧导航窗格中要添加同义词列表的索引下，请选择同义词。

2. 在同义词页面上，选择添加同义词库。

3. 在定义同义词库中，为同义词库指定名称和可选描述。

4. 在同义词库设置中，提供同义词库文件的 Amazon S3 路径。文件必须小于 5 MB。

5. 对于 IAM 角色，选择一个角色或选择创建新角色并指定角色名称以创建新角色。 Amazon Kendra 使用此角色代表您访问 Amazon S3 资源。IAM 角色的前缀为 “AmazonKendra-”。

6. 选择保存以保存配置并添加同义词库。收录同义词库后，它就会处于活动状态，结果中会突出显示同义词。要了解同义词库文件的效果，最多可能需要 30 分钟。

CLI

要使用将同义词添加到索引中 AWS CLI，请调用：create-thesaurus

aws kendra create-thesaurus \
--index-id index-id \
--name "thesaurus-name" \
--description "thesaurus-description" \
--source-s3-path "Bucket=bucket-name,Key=thesaurus/synonyms.txt" \
--role-arn role-arn

调用 list-thesauri 以查看同义词库列表：

aws kendra list-thesauri \
--index-id index-id

要查看同义词库的详细信息，请调用 describe-thesaurus：

aws kendra describe-thesaurus \
--index-id index-id \
--index-id thesaurus-id

要了解同义词库文件的效果，最多可能需要 30 分钟。
