將索引典新增至索引

下列程序顯示如何將包含同義字的索引典檔案新增至索引。您最多可能需要 30 分鐘才能看到更新的索引典檔案的效果。如需索引典檔案的詳細資訊，請參閱。建立同義字辭典檔案

Console

若要新增索引典

1. 在左側導覽窗格中，在您要新增同義字清單的索引下，選擇同義詞字典。

2. 在「同義字」頁面上，選擇「新增同義字辭典」。

3. 在定義索引典中，為您的索引典指定名稱和選擇性說明。

4. 在索引典設定中，提供索引典檔案的 Amazon S3 路徑。檔案必須小於 5 MB。

5. 對於 IAM 角色，請選取角色或選取建立新角色並指定角色名稱以建立新角色。 Amazon Kendra 使用此角色代表您存取 Amazon S3 資源。IAM 角色的前置詞為「AmazonKendra-」。

6. 選擇 [儲存] 以儲存組態並新增索引典。一旦擷取同義字辭典，它就是作用中的，且同義字會在結果中反白顯示。查看索引典檔案的效果最多可能需要 30 分鐘。

CLI

若要使用新增索引至索引 AWS CLI，請呼叫：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

呼叫list-thesauri以查看索引典清單：

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

若要檢視索引典的詳細資料，請呼叫：describe-thesaurus

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

查看索引典檔案的效果最多可能需要 30 分鐘。
