Searchservice

This microservice runs on port 8009 and enables users to search message content using Elasticsearch. Searchservice depends on Elasticsearch and RabbitMQ.

---

Expected Format

SearchService expects messages on port 5672 for the RabbitMQ fanout exchange messages, posted in the JSON document format:

{
    "_id": {
            "$oid": "664752b07daf56ec5f3e6bca"
            },
    "from": "user123",
    "to": "user321",
    "message": "Hello!",
    "date": "2024-05-17T12:50:56.992273584Z"
}

The Post Service in the example below posts messages in this format.

Endpoints

The endpoint /search allows searching across all messages for a user. You can optionally include otherUserID to search within conversations between yourself and another user.

Search in Messages

• Endpoint: /search

• Query Parameters:

  • text: The search query.
  • otherUserID (optional): Specify another user's ID to search within conversations.

• Example

or, to get all results within a conversation:

  GET /search?text=example&otherUserID=123

    volumes:
      - dbData:/var/lib/rabbitmq
    ports:
      - "15672:15672"
      - "5672:5672"
