Building a search solution for scanned images using Amazon Elasticsearch

In the previous chapters, we spoke about how you can use Amazon Lambda functions to create a serverless application. In this section, we will walk you through the following architecture to set up a scanned image-based search solution by calling the Amazon Textract and Amazon Comprehend APIs using an Amazon Lambda function. We are going to use Amazon Elasticsearch for this use case. However, you can also replace Amazon Elasticsearch with Amazon Kendra to create an ML-based search solution where you can use natural language to ask questions while searching.

Amazon S3 is used for centralized storage. Amazon Lambda functions are used as serverless event triggers when the scanned resumes are uploaded to Amazon...
