The Algolia AEM Extensions repository provides reference implementations of custom extensions for the Algolia AEM Connector, demonstrating how to enhance and customize indexing behavior for Adobe Experience Manager. It includes two main extensions: one for extracting text from PDF assets and another for extracting tags from both pages and assets, allowing developers to tailor the indexing process to their specific requirements. This project is designed for developers working with Algolia and AEM who need to implement custom indexing logic beyond the connector's default capabilities.
