+# Hybrid RRF Search
+
+This bundle implements a production-ready **Hybrid Search Pipeline** using Reciprocal Rank Fusion (RRF) and an LLM-based reranker. It allows you to search large documents with incredibly high precision by combining the best of Keyword Search (BM25) and Vector Search (Cosine Similarity), and having an LLM pick the final winners.
+
+## What is it?
+
+Pure vector search struggles with exact keyword matching (like names or IDs). Pure keyword search struggles with semantic meaning. 
+**Hybrid Search** runs both searches simultaneously, and **Reciprocal Rank Fusion (RRF)** mathematically combines their scores to bubble the most relevant passages to the top.
+
+This pipeline takes it one step further by piping those top results into an LLM (`Generate JSON` node) to act as a **Reranker**, outputting the final top 5 passages as a perfectly formatted JSON array.
+
+## Features
+
+- **Cohere Embeddings**: Uses `embed-english-v3.0` for highly accurate vector representations.
+- **Weaviate Vector DB**: Leverages Weaviate's native `rankedFusion` capabilities.
+- **Data Ingestion**: A robust `codeNode` setup for formatting raw chunks.
+- **LLM Reranking**: Uses an LLM to evaluate the top results and enforce a strict JSON output schema.
+
+## Setup Instructions
+
+1. **Import the flows**: Import this bundle into your Lamatic project.
+2. **Configure your Database**: Ensure your VectorDB is connected and configured for Hybrid RRF in the Studio integrations.
+3. **Run the Ingestion Flow**: Push your text chunks into the VectorDB.
+4. **Deploy the Search Flow**: The GraphQL API is ready to accept queries.
+
+## Usage Example
+
+Send a GraphQL request to your Lamatic endpoint:
+
+```json
+{
+  "query": "what do I do in a dust storm?"
+}
+```
+
+**Response:**
+
+```json
+{
+  "results": [
+    {
+      "id": "passage_0",
+      "content": "## 2. Dealing with Dust Storms\nIf a massive planetary dust event is detected by the orbital satellite network, all rovers must immediately return to the main garage...",
+      "score": 1
+    }
+  ]
+}
+```

+# Hybrid RRF Search Agent
+
+## Overview
+This bundle implements a **Data Retrieval and Reranking Agent**. It does not engage in conversational chat. Instead, its sole purpose is to act as an incredibly precise and intelligent search engine. 
+
+## Purpose
+In standard RAG (Retrieval-Augmented Generation) applications, the VectorDB returns results based strictly on mathematical distance. However, these results often contain noise or lack exact keyword matches.
+
+This Agent solves that by acting as a **Judge**. It receives the raw results from the VectorDB (which themselves are a fusion of keyword and vector search) and evaluates them one by one against the user's original query, assigning a relevance score from 0.0 to 1.0. 
+
+## Capabilities
+- **Hybrid Retrieval**: Queries Weaviate using both BM25 and Vector search.
+- **Data Transformation**: Uses embedded code nodes to safely stringify complex JSON objects so the LLM can read them.
+- **Relevance Scoring**: Evaluates retrieved passages purely on relevance.
+- **Strict JSON Formatting**: Enforces a strict JSON schema output so that the API always returns structured data, never raw markdown.
+
+## Guardrails
+- The agent is instructed to **ONLY** output a JSON object with a top-level `results` array.
+- It will not answer questions or generate conversational text.
+- It relies on `gemini-2.5-flash` for high-speed, structured output.

+# 🚀 Pitch: Hybrid RRF Search Bundle
+
+## The Problem with Standard RAG
+
+The biggest complaint about standard Retrieval-Augmented Generation (RAG) is that **vector search alone is not enough**.
+While vector search is great for finding semantic meaning ("planetary vehicle" matches "rover"), it is terrible at exact keyword matching. If a user searches for a specific ID like `MBA-9932-REV-B`, vector search often completely misses it.
+
+On the flip side, traditional keyword search (BM25) is great at exact matches, but terrible at understanding intent.
+
+## The Solution: Hybrid Search + Reciprocal Rank Fusion
+
+This bundle solves that problem by implementing a true **Hybrid Search Pipeline**.
+It runs both a Vector Search and a Keyword Search at the exact same time, and uses a mathematical algorithm called **Reciprocal Rank Fusion (RRF)** to combine the results. The passages that rank high in *both* searches bubble to the top.
+
+## The Secret Sauce: LLM Reranking
+
+We don't stop at RRF. This pipeline pipes the top fused results directly into an LLM (Gemini 2.5 Flash) configured with a strict JSON schema. The LLM acts as a **Judge**, reading the passages and scoring them against the user's exact query from 0.0 to 1.0.
+
+It outputs a perfectly formatted JSON object with a `results` key containing the definitive Top 5 passages, completely eliminating noise.
+
+## Why Lamatic Needs This
+
+Building an RRF pipeline with an LLM reranker usually requires writing hundreds of lines of complex orchestration code in Python or LangChain.
+With this bundle, developers can import a production-ready RRF pipeline directly into their Lamatic workspace and deploy it instantly as a scalable GraphQL API. It perfectly showcases Lamatic's ability to orchestrate multi-step data transformations and structured LLM outputs!

+
+## 1. Primary Airlock Procedures
+All personnel must use Airlock X-42 when exiting the habitat for surface operations. The secondary airlock, Y-17, is strictly reserved for emergency decompression events. Before opening the outer door of X-42, the suit pressure gauge must read exactly 4.3 PSI.
+
+## 2. Dealing with Dust Storms
+If a massive planetary dust event is detected by the orbital satellite network, all rovers must immediately return to the main garage. Do not attempt to drive through low visibility. The solar panels will automatically retract to prevent abrasive damage. Switch to the geothermal backup generator located in Sector 7.
+
+## 3. Hydroponics Bay Management
+The hydroponics bay provides 80% of our daily caloric intake. The primary crop is engineered sweet potatoes (Strain SP-Alpha-9). The nutrient solution must be kept at a pH of exactly 6.2. If the pH drops below 5.5, the automated alarm system will sound a Code Green alert.
+
+## 4. Communication Protocols
+Direct communication with Earth has a delay of 3 to 22 minutes depending on planetary alignment. For emergency medical consultations, use the Quantum Encrypted Channel (Frequency 902.4 MHz). Routine daily reports should be batched and sent via the standard high-gain antenna at 0400 UTC.
+
+## 5. Rover Maintenance
+The primary transport vehicle is the 'Ares Rover Model 4'. The battery cells on this model require a full discharge and recharge cycle every 30 Martian days (Sols). Never mix synthetic grease with the axel lubricants, as the extreme cold will cause it to solidify and crack the housing.
