[edigu]

• Create a Search module for various full-text search requirements.
• Search module SHOULD support both Elasticsearch and Solr selectively via different adapters and configurations.
• Consider separating Index (Create, Update or Delete documents) and Query services.
• Create two example services UserQueryService and UserIndexService
• Update, modify or delete documents in UserIndexService and search users in UserQueryService.
• Consider creating a CLI route in Search module and add some example interfaces for scenarios such as deleting a user by id, indexing all users via CLI.
• Write documentation.
