+- Creates vector embeddings from uploaded content using Weaviate
+- Uses Query Decomposition for focused retrieval
+- Uses Reciprocal Rank Fusion (RRF) for intelligent result merging

+Think of Middleware like a Security Guard or a Receptionist at the entrance of a building (your App).
+
+Entry: Every visitor (Request) has to stop at the desk first. The receptionist notes the time they arrived.
+
+Pass-through: The receptionist lets them go up to the specific office they need (The Endpoint).
+
+Exit: When the visitor comes back down to leave, they pass the receptionist again. The receptionist notes the time they left and calculates how long the visit took.
+
+The Flow of Your Code
+Here is exactly what happens when a user hits your API (e.g., GET /home):
+
+1. The Setup (Global Scope)
+Before any request comes in, Python reads the file.
+
+It sets up a logger (a tool to write messages).
+
+It creates a FileHandler to write those messages to logging.txt.
+
+2. The Request Arrives
+A user sends a request. The FastAPI app receives it. Because you added app.add_middleware(RequestLoggingMiddleware), the request does not go straight to your function. It goes to your RequestLoggingMiddleware class first.
+
+3. The dispatch Method (The Core)
+This is the heart of the middleware. The dispatch function is triggered.
+
+Step A: Start the Clock start_time = time.time() You take a snapshot of the current time.
+
+Step B: Pass the Baton (call_next) response = await call_next(request) This line is crucial. It tells FastAPI: "Okay, I'm done with my pre-checks. Go run the actual function for this route (e.g., login, get_users, etc.) and bring me back the result."
+
+Step C: The Return Trip Once the actual route finishes, the code resumes exactly where it left off (after call_next). duration = (time.time() - start_time) * 1000 You check the time again to see how many milliseconds passed.
+
+Step D: Log It logger.info(...) You write a line into your log file saying: "Hey, the request to /home took 150ms and returned a 200 OK status."
+
+
+
+
+For incoming requests: C → B → A → Route
+For outgoing responses: A → B → C → Client
+
+It's like a stack - last in, first out!
+
+Think of it like security checkpoints:
+
+You add checkpoint A, B, C
+Visitor goes through C first (newest), then B, then A
+On the way out: A, then B, then C
+
+# 1. Middleware order is wrong
+app.add_middleware(CORSMiddleware, ...)    # Added first
+app.add_middleware(RequestLoggingMiddleware)  # Added last
+# But they run in REVERSE order! Logging runs before CORS!
+
+# 2. CORS is too permissive
+allow_origins= ['*']  # ❌ Anyone from anywhere can access!
+
+# 3. No rate limiting
+# Missing: app.add_middleware(RateLimitingMiddleware)
