+
+## 🔍 Relevance Score Calculation
+
+The system uses sophisticated relevance scoring to determine how well retrieved documents align with user queries. This process is crucial for selecting the most pertinent information for generating accurate and contextually appropriate responses.
+
+### How Relevance Scores Work
+
+#### 1. **Document Embedding Process**
+- **Page Segmentation**: Each document page is processed as a complete unit
+- **Multimodal Encoding**: Both text and visual elements are captured using ColPali embeddings
+- **Vector Representation**: Pages are transformed into high-dimensional numerical vectors (typically 768-1024 dimensions)
+- **Semantic Capture**: The embedding captures semantic meaning, not just keyword matches
+
+#### 2. **Query Embedding**
+- **Query Processing**: User queries are converted into embeddings using the same ColPali model
+- **Semantic Understanding**: The system understands query intent, not just literal words
+- **Context Preservation**: Query context and meaning are maintained in the embedding
+
+#### 3. **Similarity Computation**
+- **Cosine Similarity**: Primary similarity measure between query and document embeddings
+- **Dot Product**: Alternative similarity calculation for high-dimensional vectors
+- **Normalized Scores**: Similarity scores are normalized to a 0-1 range
+- **Distance Metrics**: Lower distances indicate higher relevance
+
+#### 4. **Score Aggregation & Ranking**
+- **Individual Page Scores**: Each page gets a relevance score based on similarity
+- **Collection Diversity**: Scores are adjusted to promote diversity across document collections
+- **Consecutive Page Optimization**: Adjacent pages are considered for better context
+- **Final Ranking**: Pages are ranked by their aggregated relevance scores
+
+### Relevance Score Interpretation
+
+| Score Range | Relevance Level | Description |
+|-------------|----------------|-------------|
+| 0.90 - 1.00 | **Excellent** | Highly relevant, directly answers the query |
+| 0.80 - 0.89 | **Very Good** | Very relevant, provides substantial information |
+| 0.70 - 0.79 | **Good** | Relevant, contains useful information |
+| 0.60 - 0.69 | **Moderate** | Somewhat relevant, may contain partial answers |
+| 0.50 - 0.59 | **Basic** | Minimally relevant, limited usefulness |
+| < 0.50 | **Poor** | Not relevant, unlikely to be useful |
+
+### Example Relevance Calculation
+
+**Query**: "What are the safety procedures for handling explosives?"
+
+**Document Pages**:
+1. **Page 15**: "Safety protocols for explosive materials" → Score: 0.95 (Excellent)
+2. **Page 23**: "Equipment requirements for explosive handling" → Score: 0.92 (Very Good)
+3. **Page 8**: "General laboratory safety guidelines" → Score: 0.88 (Very Good)
+4. **Page 45**: "Chemical storage procedures" → Score: 0.65 (Moderate)
+
+**Selection Process**:
+- Pages 15, 23, and 8 are selected for their high relevance
+- Page 45 is excluded due to lower relevance
+- The system ensures diversity across different aspects of safety procedures
+
+### Advanced Features
+
+#### **Multi-Modal Relevance**
+- **Visual Elements**: Images, charts, and diagrams contribute to relevance scores
+- **Text-Vision Alignment**: ColPali captures relationships between text and visual content
+- **Layout Understanding**: Document structure and formatting influence relevance
+
+#### **Context-Aware Scoring**
+- **Query Complexity**: Complex queries may retrieve more pages with varied scores
+- **Cross-Reference Detection**: Pages that reference each other get boosted scores
+- **Temporal Relevance**: Recent documents may receive slight score adjustments
+
+#### **Quality Assurance**
+- **Score Verification**: System validates that selected pages meet minimum relevance thresholds
+- **Diversity Optimization**: Ensures selected pages provide comprehensive coverage
+- **Redundancy Reduction**: Avoids selecting multiple pages with very similar content
+
+### Configuration Parameters
+
+```env
+# Relevance scoring configuration
+metrictype=IP          # Inner Product similarity
+mnum=16                # Number of connections in HNSW graph
+efnum=500              # Search depth for high-quality results
+topk=50                # Maximum results to consider
+```
+
+### Performance Impact
+
+- **Search Speed**: Relevance scoring adds minimal overhead (~10-50ms per query)
+- **Accuracy**: High-quality embeddings ensure accurate relevance assessment
+- **Scalability**: Efficient vector operations support large document collections
+- **Memory Usage**: Optimized to handle thousands of document pages efficiently
+
+## 🔒 Security Considerations
+
+### Production Deployment
+1. **HTTPS**: Always use HTTPS in production
+2. **Environment Variables**: Store sensitive data in environment variables
+3. **Database Security**: Use production-grade database (PostgreSQL/MySQL)

+
+# Rate limiting
+limiter = Limiter(
+    app,
+    key_func=get_remote_address,
+    default_limits=["200 per day", "50 per hour"]
+)
+
+# Security headers
+@app.after_request
+def add_security_headers(response):
+    response.headers['X-Content-Type-Options'] = 'nosniff'
+    response.headers['X-Frame-Options'] = 'DENY'
+    response.headers['X-XSS-Protection'] = '1; mode=block'
+    return response
+```
+

This analysis incorporates information from all three pages, detailing attackers, targets, locations, weapons, and resulting damage/casualties."
+Measurement,1,"The conflict stems from a series of escalating actions initiated by Israel, targeting Iran’s nuclear program.  Page 1 highlights that this began with Israeli strikes on nuclear and military sites in Iran, prompting retaliatory attacks by Iran targeting Israel.  The situation is highly volatile, with both sides engaged in rhetorical threats and actual military action, and the US considering its involvement (Page 1).  The Israeli Prime Minister, Benjamin Netanyahu, justified the attacks as a pre-emptive measure to prevent Iran from developing nuclear weapons, claiming they could produce one ""in a very short time"" if not stopped (Page 1). The conflict centers around concerns over Iran’s nuclear program and the potential for developing a nuclear weapon, and further details indicate that Iran is under investigation for possibly building these weapons (Page 3)."
+Measurement,13,**Timeline: 13-15 June 2025**
+Measurement,2,"*   **Page 2:** This page provides a timeline of the immediate retaliatory actions. It details Iran launching around 100 missiles towards Israel on June 13th, with the majority being intercepted by Israel’s Iron Dome system. There is mention of the reporting of 78 people being injured by Friday evening. Page 2 also highlights coordination between Israel and Washington on Iran and notes a reported Iranian missile directly hitting a hospital in Beersheba, Southern Israel (Page 2)."
