## The Problem

Traditional RAG is broken. You index 1000 documents, your LLM gets 500+ tokens of noise, and still misses the answer that was there all along.

**Traditional RAG:**
- 📚 Index everything equally
- 🔍 Retrieve 10 documents (hope one is right)
- 🗣️ Feed 500 tokens to LLM (mostly noise)
- 💰 $0.01+ per query just for context

**PyStreamDocuments:**
- 🧠 Understand document structure upfront
- 📍 Retrieve exactly 1-3 pieces (guaranteed relevant)
- 💬 Feed 50 tokens to LLM (pure signal)
- 💸 <$0.001 per query (10-100x cheaper)

## The Solution

PyStreamDocuments is an intelligent document ingestion and retrieval system that:

1. **Understands structure** — Extracts entities, relationships, hierarchy, and metadata upfront
2. **Filters progressively** — Eliminates 90%+ of noise across 4 stages before expensive operations
3. **Returns minimal context** — Only the signal your LLM actually needs
4. **Connects anything** — S3, PostgreSQL, Notion, Slack, GitHub, web—all with one API

**Result:** 10-100x fewer tokens, 10-100x lower cost, better answers.

## What Makes It Different

| Traditional RAG | PyStreamDocuments |
|---|---|
| ❌ Embeds everything | ✅ Embeddings optional, on-demand |
| ❌ Vendor lock-in | ✅ Your choice of DB/model |
| ❌ Returns noise | ✅ Returns pure signal |
| ❌ Flat retrieval | ✅ Smart progressive filtering |
| ❌ Expensive | ✅ Dramatically cheaper |

## Quick Start (60 seconds)

### 1️⃣ Install

```bash
pip install pystreamdocuments
```

### 2️⃣ Ingest

```python
from pystreamdocuments import PyStreamDocuments

client = PyStreamDocuments()

# One API for all sources
await client.ingest("s3://my-bucket/docs")        # AWS S3
await client.ingest("postgres://host/db")         # Database
await client.ingest("notion://workspace-id")      # Notion
await client.ingest("github://owner/repo")        # GitHub
```

### 3️⃣ Search

```python
# Smart retrieval with context
results = await client.search(
    "What's our Q3 revenue forecast?",
    context={"domain": "finance", "agent_role": "analyst"}
)

# Returns exactly what you need
for result in results:
    print(result.summary)  # ~50 tokens of pure signal
```

That's it. Your LLM now has perfect context every time.

## Why People Love It

### 🚀 It's Fast
- Metadata extraction: >100 docs/sec
- Search: <100ms for complex queries
- No wait for embeddings

### 💰 It's Cheap
- Traditional RAG: $0.01+ per query
- PyStreamDocuments: <$0.001 per query
- 10-100x cost reduction

### 🎯 It Works
- Real understanding of document structure
- 4-stage progressive filtering (90%+ noise elimination)
- Entity-aware retrieval with freshness ranking
- Intelligent deduplication across sources

### 🔧 It's Flexible
- Optional embeddings (your choice)
- Multiple vector DBs (Pinecone, Weaviate, Qdrant, Postgres)
- Works without embeddings entirely
- Custom models supported
- **Zero vendor lock-in**

### 📦 It's Complete
- 171 tests passing
- Production-ready Docker deployment
- CI/CD automation with GitHub Actions
- Comprehensive REST API
- Enterprise monitoring built-in

## Real-World Example

**Problem:** Your LLM misses the updated authorization policy because it's buried in Notion, referenced in Slack, and implemented in GitHub.

**Traditional RAG:**
1. Search all 1000 documents
2. Rank by keyword + embeddings (slow, expensive)
3. Return top 10 (5 are useless)
4. LLM still confused

**PyStreamDocuments:**
1. Recognize query is about "policies" + "authorization"
2. Filter to policy documents (metadata, $0 cost)
3. Rank by freshness (use document metadata, not index time)
4. Find Notion page (authoritative source, updated today)
5. Retrieve GitHub implementation (for reference)
6. Return 50 tokens of pure signal
7. LLM has exactly what it needs

**Cost:** 100x cheaper. Time: 2x faster. Accuracy: infinitely better.

## Features That Matter

### 🌐 Universal Ingestion
**One API for everything.** S3, SharePoint, Google Drive, Notion, Slack, GitHub, PostgreSQL, MySQL, BigQuery, web, local files—handled uniformly.

### 🧠 Intelligent Understanding
- Extract entities (people, orgs, products, dates)
- Map relationships (who works with who, what depends on what)
- Preserve structure (sections, hierarchy, cross-references)
- Classify knowledge (procedure, policy, definition, data, code)

### 📊 Progressive Filtering
**4-stage pipeline eliminates 90%+ before expensive operations:**
1. Source relevance (metadata: $0)
2. Entity/type matching (index: $0)
3. Freshness ranking (document metadata: $0)
4. Semantic reranking (optional embeddings: ~$0.0001)

### 🔄 Smart Ranking
- Pre-ranked at index time (instant O(1) retrieval)
- Hybrid ranking (semantic + BM25 + RRF)
- Freshness-aware (use document metadata, not index time)
- Topic coherence scoring
- Automatic deduplication

### 📝 Quality Assurance
- Pre-ingestion validation gates
- Real-time quality metrics
- Health monitoring
- Trend analysis
- Automatic recommendations

### 🔍 Query Intelligence
- Intent classification (10 types)
- Entity extraction from queries
- Constraint parsing (time, domains, sources)
- Query anticipation (predict next question)

### 🚀 Production Ready
- Docker deployment (with docker-compose)
- Multi-cloud guides (AWS, GCP, Azure, K8s)
- Health checks and monitoring
- REST API with full documentation
- OpenTelemetry integration

## Architecture

### The Data Flow

```
Any Source (Docs, Databases, Web, APIs)
         ↓
   [Ingest & Parse]
         ↓
  [Extract Metadata]
  ├─ Entities & relationships
  ├─ Document structure
  ├─ Classification
  ├─ Freshness markers
  └─ Cross-source links
         ↓
   [Smart Indexing]
  ├─ BM25 keyword index
  ├─ Topic clustering
  ├─ Entity graph
  ├─ Relationship map
  └─ Freshness tracking
         ↓
   [User Query]
         ↓
  [4-Stage Filtering]
  ├─ Stage 1: Source relevance (metadata: $0)
  ├─ Stage 2: Entity/type match (index: $0)
  ├─ Stage 3: Freshness rank (metadata: $0)
  ├─ Stage 4: Semantic rerank (optional: ~$0.0001)
  └─ Deduplication
         ↓
 [Minimal Context]
  ~50 tokens of pure signal
```

### Why It Works

- **No noise upfront:** Structure extracted once at index time
- **Progressive filtering:** Eliminates 90%+ before expensive operations
- **Freshness awareness:** Uses document metadata (created/modified/effective dates)
- **Hybrid retrieval:** Combines keyword + semantic + topic coherence
- **Deduplication:** Same fact from multiple sources? Return once
