Implement Mock Cognitive Search Service

[jasonmorais]

Cognitive Search task description

Task Overview

Develop a ServiceSearch infrastructure service for the ShareThrift application that abstracts search capabilities. This service should implement ServiceBase from @cellix/api-services-spec and allow seamless switching between Azure Cognitive Search and a local mock alternative (e.g., LiQE or Lunr.js) based on runtime configuration (via environment variables). Refer to AHP Cognitive Search implementation to understand what capabilities the search service should provide.

Requirements

• Implement a ServiceSearch class/interface that extends ServiceBase and serves as the entry point for all search operations in the application.
• The service should detect configuration from environment variables to determine whether to use Azure Cognitive Search or a mock implementation.
• Explore and document local search options such as LiQE and Lunr.js for the mock implementation.
• Provide a mock implementation that mimics the Azure Cognitive Search API surface as closely as possible.
• Ensure easy extensibility for future search providers.
• Add example usage/tests demonstrating both real and mock search flows.

Deliverables

• ServiceSearch infrastructure service class/interface implementing ServiceBase from @cellix/api-services-spec
• Azure Cognitive Search integration
• Mock implementation using LiQE and/or Lunr.js
• Documentation and example code for switching between implementations using environment variables
• Unit/integration tests for both modes
