## Choosing Between Semantic and Vector Search

| Use Case | Recommended | Why |
|----------|-------------|-----|
| Exploratory research | Semantic | LLM extracts keywords, generates summary |
| Known-topic monitoring | Vector | Faster, direct matching, no LLM overhead |
| Batch processing | Vector | 5x faster per request |
| Answering complex questions | Semantic | AI summary synthesizes insights |
| Real-time dashboards | Vector | Low latency (~5s vs ~20s) |

## Best Use Cases (Tested)

| Use Case | Effectiveness | Why |
|----------|--------------|-----|
| Product comparisons (A vs B) | ⭐⭐⭐⭐⭐ | Reddit loves debates |
| Tool/app recommendations | ⭐⭐⭐⭐⭐ | High-intent discussions |
| Side hustle/money topics | ⭐⭐⭐⭐⭐ | Engaged communities |
| Pain point discovery | ⭐⭐⭐⭐ | Emotional posts rank well |
| Health questions | ⭐⭐⭐⭐ | Active health subreddits |
| Technical how-to | ⭐⭐⭐ | Better to search specific subreddits |
| Abstract market research | ⭐⭐ | Too vague for semantic search |
| Non-English queries | ⭐ | Reddit is English-dominant |

## Query Strategies

### ✅ Excellent Queries (relevance 0.70+)

**Product Comparisons** (best results!):
```
"Notion vs Obsidian for note taking which one should I use"
→ Relevance: 0.72-0.81 | Found: Detailed comparison discussions, user experiences

"why I switched from Salesforce to HubSpot honest experience"  
→ Relevance: 0.70-0.73 | Found: Migration stories, feature comparisons
```

**Side Hustle/Money Topics:**
```
"side hustle ideas that actually make money not scams"
→ Relevance: 0.70-0.77 | Found: Real experiences, specific suggestions
```

### ✅ Good Queries (relevance 0.60-0.69)

**Pain Point Discovery:**
```
"I hate my current CRM it is so frustrating"
→ Relevance: 0.60-0.64 | Found: Specific CRM complaints, feature wishlists
```

**Tool Evaluation:**
```
"AI tools that actually save time not just hype"
→ Relevance: 0.64-0.65 | Found: Real productivity gains, tool recommendations
```

### ❌ Weak Queries (avoid these patterns)

**Too Abstract:** "business opportunity growth potential" → 0.52-0.58
**Non-English:** "学习编程最好的方法" → 0.45-0.51

### Query Formula Cheat Sheet

| Goal | Pattern | Relevance |
|------|---------|-----------|
| Compare products | "[A] vs [B] which should I use" | 0.70-0.81 |
| Find switchers | "why I switched from [A] to [B]" | 0.70-0.73 |
| Money/hustle topics | "[topic] that actually [works/makes money] not [scam/hype]" | 0.70-0.77 |
| App recommendations | "[category] apps which one is [accurate/best] and why" | 0.67-0.72 |
| Pain points | "I hate my current [tool] it is so [frustrating/slow]" | 0.60-0.64 |
| Solutions seeking | "[problem] tried everything what actually works" | 0.60-0.63 |

## Example Workflows

**Market Research:**
```bash
curl -X POST https://reddapi.dev/api/v1/search/semantic \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "frustrated with project management tools switching from Jira", "limit": 50}'
```

**Brand Monitoring (fast):**
```bash
curl -X POST https://reddapi.dev/api/v1/search/vector \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "your-brand-name reviews complaints", "limit": 30}'
```

**Deep Research (combine both):**
1. Vector search first to quickly scope the landscape
2. Semantic search for deep analysis on specific angles

**Time-Filtered Sentiment Tracking:**
```bash
curl -X POST https://reddapi.dev/api/v1/search/vector \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "ChatGPT quality", "start_date": "2026-01-01", "end_date": "2026-03-18"}'
```

## Tips

1. **Natural language works best** - Ask questions like a human would
2. **Include context** - "for small business" or "as a developer" improves results
3. **Combine emotion words** - "frustrated", "love", "hate", "wish" find stronger opinions
4. **Filter by engagement** - High upvotes/comments = validated pain points
5. **Use vector search for speed** - ~5s vs ~20s for semantic
6. **Use date filters** - Track sentiment changes over time periods
