### Configuration on Amazon Kendra console

(1) Create Index

An index provides search results for documents and frequently asked questions (FAQ) that it has indexed. An index can contain documents that are indexed from a data source, documents that are added directly to the index, and FAQs.

(2) Create Data Source

A data source is a location, such as an Amazon Simple Storage Service (Amazon S3) bucket, where you store the documents for indexing. Data sources can be automatically synchronized with an Amazon Kendra index so that new, updated, or deleted documents in the source repositories are included in searches. Supported data sources are:

* Amazon S3 buckets
* Amazon RDS for MySQL and Amazon RDS for PostgreSQL databases
* Microsoft OneDrive for Business
* Microsoft SharePoint Online
* Salesforce sites
* ServiceNow instances

Supported document formats are plain text, Microsoft Word, Microsoft PowerPoint, HTML, and PDF
