+# TODO: add websocket to full text search postgres database for nonsense description
+
+# To add a WebSocket to full text search a PostgreSQL database for the `nonsense` description, you can use the `websockets` library in Python. Here's a step-by-step plan:
+#
+# 1. Install the `websockets` library if you haven't done so already.
+# 2. Create a new WebSocket route in your FastAPI application.
+# 3. In the WebSocket route, accept a search query from the client.
+# 4. Use the search query to perform a full text search on the `nonsense` table in your PostgreSQL database.
+# 5. Send the search results back to the client through the WebSocket connection.
+#
+# Here's how you can implement this:
+#
+# ```python
+# import websockets
+# from fastapi import WebSocket
+# from sqlalchemy import text
+#
+# router = APIRouter()
+#
+# @router.websocket("/ws/nonsense")
+# async def websocket_endpoint(websocket: WebSocket):
+#     await websocket.accept()
+#     while True:
+#         data = await websocket.receive_text()
+#         query = text(f"""
+#             SELECT * FROM nonsense
+#             WHERE to_tsvector('english', description) @@ plainto_tsquery('english', :q)
+#         """)
+#         result = await db_session.execute(query, {"q": data})
+#         await websocket.send_json(result.fetchall())
+# # ```
+#
+# This code creates a new WebSocket route at `/ws/nonsense`. When a client connects to this route and sends a message, the message is used as a search query in a full text search on the `nonsense` table. The search results are then sent back to the client through the WebSocket connection.
+#
+# Please note that this is a basic implementation and might need adjustments based on your specific needs. For example, you might want to add error handling, handle disconnections, or format the search results before sending them back to the client.
