Building the Perfect Document Search Indexing Solution
In the fast-paced world of modern business, managing and retrieving large volumes of documents is essential for maintaining a competitive edge. However, traditional methods of storing and searching for documents can be time-consuming and inefficient, especially when dealing with handwritten content. But what if there was a way to process documents intelligently and make them easily searchable with high accuracy? Enter Amazon Textract, AWS’s Intelligent Document Processing service, combined with the powerful search capabilities of OpenSearch.
In this article, we’ll take you on a journey to rapidly build and deploy a document search indexing solution that will revolutionize the way your organization extracts insights from documents. Whether you’re in HR searching for specific clauses in employee contracts or a financial analyst sorting through mountains of invoices for payment data, this solution is tailor-made to provide you with the information you need swiftly and accurately.
The Proposed Solution
With our proposed solution, your documents are automatically ingested, their content parsed, and then indexed into a highly responsive and scalable OpenSearch index. This is made possible through a combination of technologies including Amazon Textract, AWS Lambda, Amazon S3, and Amazon OpenSearch Service.
Let’s dive into the workflow of this solution and explore how each of these technologies contributes to the seamless document processing and indexing.
Step 1: Document Ingestion
The first step is to upload your documents in PDF, TIFF, JPEG, or PNG format to an Amazon S3 bucket. This is where your documents will be stored for processing and indexing.
Step 2: Document Splitting
The DocumentSplitter, an AWS Lambda function, splits your documents into manageable chunks of up to 2500 pages. This means that even if you have documents with more than 3000 pages, the process will still work efficiently, ensuring accurate indexing and page numbering.
Step 3: Text Extraction with Amazon Textract
Next, each chunk of the document is processed by Amazon Textract. This powerful AI-based service extracts text and data from your documents with high accuracy. It utilizes asynchronous API calls with Amazon SNS notifications and OutputConfig to store the extracted data in your Amazon S3 bucket.
Step 4: Context Enrichment
In this step, the workflow enriches the Step Functions context with additional information that should be searchable in the OpenSearch index. You can include any relevant data such as file names, page numbers, or additional classification information to enhance the search experience.
Step 5: Generating OpenSearch Batch
The GenerateOpenSearchBatch task combines the extracted data from Amazon Textract with the enriched context information. It prepares a file optimized for batch import into OpenSearch, ensuring efficient indexing of the documents.
Step 6: Indexing in OpenSearch
The OpenSearchPushInvoke, an AWS Lambda function, sends the batch import file to the OpenSearch index. This makes the indexed data available for search through OpenSearch’s powerful search capabilities. You can configure OpenSearch according to your organization’s requirements, such as search instances, volume size, and version.
Step 7: Finalizing the Workflow
The final step, TaskOpenSearchMapping, clears the context to ensure it doesn’t exceed the Step Functions quota. This ensures smooth execution of the workflow without any storage or processing limitations.
Deploying the Solution
To deploy this powerful document search indexing solution, follow these steps:
1. Set up the prerequisites, including an AWS account, AWS CDK, Python, and Docker.
2. Clone the repository and install the required dependencies.
3. Deploy the OpenSearchWorkflow stack using the CDK command.
The deployment process will create a Step Functions workflow that is triggered whenever a document is uploaded to the specified Amazon S3 bucket. The document will be processed and indexed in the OpenSearch cluster.
Testing and Search
To test the solution, you can use a sample document provided by Amazon Textract. Follow the instructions in the article to download and upload the sample document to the specified S3 bucket. You can then monitor the progress of the document processing through the Step Functions workflow executions.
Once the process is complete, you can validate the document’s indexing by creating an Amazon Cognito user for authentication. This user will have access to the OpenSearch Dashboard, where you can search for documents using keywords or other criteria.
Conclusion
With the intelligent document processing capabilities of Amazon Textract and the powerful search capabilities of OpenSearch, you can revolutionize your organization’s document management and retrieval processes. By following the step-by-step guide in this article, you can quickly deploy a robust document search indexing solution that will give you unprecedented speed and accuracy in accessing critical information. Whether you’re just starting your digital transformation journey or looking to optimize your existing document processing workflows, AWS Intelligent Document Processing and OpenSearch are your ultimate tools for success.
