**Date**: 2025-01-29  
**Status**: Comparison of Current Implementation vs Exa API Documentation

## 📊 Summary

This document compares our current Exa implementation with the official Exa API documentation to identify missing options and configuration gaps.

---

## ✅ Currently Supported Options

### Main Search Parameters
1. ✅ **`type`** - Search type (auto, neural, fast, deep)

   - **Frontend**: `exa_num_results` input (5-25 limit shown, but API supports up to 100)
   - **Backend**: Uses `config.max_sources` (capped at 25), should use `config.exa_num_results`
   - **Status**: Partially supported (needs to use `exa_num_results` instead of `max_sources`)

### Contents Parameters (Currently Hardcoded)
6. ⚠️ **`text`** - Full page text retrieval

9. ⚠️ **`context`** - Context string for RAG
   - **Current**: Not used (we have `exa_context` boolean in config but not applied)
   - **Should be**: Configurable via `exa_context` (boolean) or `exa_context_max_characters` (object)

## 🔧 Implementation Gaps

### 1. Date Filter Not Applied
- **Issue**: `exa_date_filter` exists in config but is not passed to Exa API
- **Fix**: Map `exa_date_filter` → `startPublishedDate` in `exa_provider.py`

### 2. Context Not Applied
- **Issue**: `exa_context` boolean exists but is not used
- **Fix**: Apply `context` parameter based on `exa_context` value

### 3. Num Results Uses Wrong Field
- **Issue**: Uses `config.max_sources` instead of `config.exa_num_results`
- **Fix**: Use `config.exa_num_results` if available, fallback to `max_sources`

### 4. Contents Parameters Hardcoded
- **Issue**: `text`, `highlights`, `summary` are hardcoded
- **Fix**: Make them configurable via ResearchConfig

---

## 📋 Recommended Priority

### Priority 1: Fix Existing Config Not Applied
1. ✅ Apply `exa_date_filter` → `startPublishedDate`
2. ✅ Apply `exa_context` → `context`
3. ✅ Use `exa_num_results` instead of `max_sources`

### Priority 2: Make Contents Configurable
4. ✅ Make `text.max_characters` configurable
5. ✅ Make `highlights` configurable (num_sentences, highlights_per_url, query)
6. ✅ Make `summary.query` configurable

### Priority 3: Add Common Date Filters
7. ✅ Add `endPublishedDate` support
8. ✅ Add `startCrawlDate` / `endCrawlDate` support (if needed)

### Priority 4: Add Text Filters (If Needed)
9. ✅ Add `includeText` / `excludeText` support (if needed)

### Priority 5: Advanced Options (Low Priority)
10. ✅ Add `userLocation`, `moderation`, `livecrawl`, `subpages`, `extras` (if needed)

---

## 🎯 Current Status

**Total Exa API Options**: ~23 options  
**Currently Supported**: 5 fully, 4 partially  
**Missing**: 14 options  
**Hardcoded**: 3 options (text, highlights, summary)

**Recommendation**: Focus on Priority 1 and 2 to make existing config work and make contents configurable.

## ✅ Recent Fixes (2025-01-29)

### Fixed Critical Issues
1. ✅ **Updated `type` enum**: Removed `deep`, added `keyword` and `fast` to match latest API
2. ✅ **Updated `category` enum**: Removed `movie` and `song`, kept `linkedin profile` 
3. ✅ **Applied `exa_date_filter`**: Now maps to `start_published_date` parameter
