# Meilisearch Integration
|
||||
|
||||
EasyStream now includes full-text search powered by Meilisearch v1.6.
|
||||
|
||||
## Features
|
||||
|
||||
- ⚡ **Blazing fast** full-text search across video titles, descriptions, tags
|
||||
- 🔍 **Autocomplete** suggestions based on trending queries and video titles
|
||||
- 🎯 **Advanced filters**: category, duration range, upload date, content type
|
||||
- 📊 **Faceted search** with result counts per filter
|
||||
- 🔥 **Trending queries** tracking for popular searches
|
||||
- 🎨 **Modern UI** with real-time autocomplete
|
||||
|
||||
## Setup
|
||||
|
||||
### 1. Start Meilisearch
|
||||
|
||||
The Meilisearch service is already configured in `docker-compose.yml`. Start it with:
|
||||
|
||||
```bash
|
||||
docker-compose up -d meilisearch
|
||||
```
|
||||
|
||||
### 2. Initialize Index
|
||||
|
||||
Run the indexer to create the search index and configure settings:
|
||||
|
||||
```bash
|
||||
docker-compose exec php php app_scripts/search/indexer.php init
|
||||
```
|
||||
|
||||
### 3. Index Videos
|
||||
|
||||
Perform a full reindex of all existing videos:
|
||||
|
||||
```bash
|
||||
docker-compose exec php php app_scripts/search/indexer.php reindex
|
||||
```
|
||||
|
||||
This will batch-index all public videos in chunks of 100.
|
||||
|
||||
## Usage
|
||||
|
||||
### Search API
|
||||
|
||||
**Endpoint:** `/api/search.php`
|
||||
|
||||
**Parameters:**
|
||||
- `q` (required): Search query
|
||||
- `category`: Filter by category
|
||||
- `duration`: Filter by duration range (`under_1min`, `1_5min`, `5_10min`, `10_20min`, `over_20min`)

|
||||

|
||||
- `limit`: Results per page (default 20, max 100)
|
||||
|
||||
**Example:**
|
||||

|
||||
curl "http://localhost:8083/api/search.php?q=tutorial&category=education&duration=5_10min&page=1&limit=20"
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": {
|
||||
"query": "tutorial",
|
||||

|
||||

|
||||

|
||||
"limit": 20,
|
||||
"facets": {
|
||||
"category": {"education": 87, "entertainment": 55},
|
||||
"duration_range": {"5_10min": 42, "10_20min": 100}
|
||||
},
|
||||
"processing_time_ms": 12
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Autocomplete API
|
||||
|
||||
**Endpoint:** `/api/search_autocomplete.php`
|
||||
|
||||
**Parameters:**
|
||||
- `q` (required): Partial query (minimum 2 characters)
|
||||
|
||||
**Example:**

|
||||
curl "http://localhost:8083/api/search_autocomplete.php?q=tut"
|
||||
```
|
||||

|
||||

|
||||

|
||||

|
||||

|
||||
"tutorials for beginners",
|
||||
"tutorial python",
|
||||
"tutorial video editing"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Indexing
|
||||
|
||||
### Incremental Indexing
|
||||
|
||||
When a video is uploaded, updated, or deleted, update the search index:
|
||||
|
||||
```php
|
||||
require_once 'app_scripts/search/indexer.php';
|
||||
$indexer = new MeilisearchIndexer();
|
||||
|
||||
// Index new/updated video
|
||||
$indexer->indexVideo($video_id);
|
||||
|
||||
// Remove deleted video
|
||||
$indexer->removeVideo($video_id);
|
||||
```
|
||||
|
||||
### Automated Reindexing
|
||||
|
||||
For large sites, add a cron job to periodically reindex:
|
||||
|
||||
```bash
|
||||
# Reindex every 6 hours
|
||||
0 */6 * * * cd /srv/easystream && php app_scripts/search/indexer.php reindex >> /var/log/meilisearch-indexer.log 2>&1
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Variables
|
||||
|
||||
Set in `docker-compose.yml` or `.env`:
|
||||
|
||||
```env
|
||||
MEILI_HOST=http://meilisearch:7700
|
||||
MEILI_MASTER_KEY=changeme_meilisearch_master_key
|
||||
MEILI_ENV=production
|
||||
```
|
||||
|
||||
⚠️ **Security:** Change `MEILI_MASTER_KEY` to a strong random key in production!
|
||||
|
||||
### Index Settings
|
||||
|
||||
The indexer automatically configures:
|
||||
|
||||
- **Searchable attributes:** `title`, `description`, `tags`, `category`, `username`
|
||||
- **Filterable attributes:** `category`, `content_type`, `duration_range`, `upload_date`, `is_live`, `privacy`
|
||||
- **Sortable attributes:** `upload_date`, `view_count`, `like_count`, `duration`
|
||||
- **Ranking rules:** Words → Typo → Proximity → Attribute → Sort → Exactness
|
||||
|
||||
Customize in `app_scripts/search/indexer.php` → `initializeIndex()`.
|
||||
|
||||
## Database Schema
|
||||
|
||||
The integration adds one table for trending query tracking:
|
||||
|
||||
```sql
|
||||
CREATE TABLE db_search_queries (
|
||||
query_id INT AUTO_INCREMENT PRIMARY KEY,
|
||||
query VARCHAR(255) NOT NULL UNIQUE,
|
||||
search_count INT DEFAULT 1,
|
||||
last_searched DATETIME,
|
||||
created_at DATETIME,
|
||||
INDEX (search_count),
|
||||
INDEX (last_searched)
|
||||
);
|
||||
```
|
||||
|
||||
Run the migration:
|
||||
|
||||
```bash
|
||||
docker-compose exec db mysql -u easystream -peasystream easystream < __install/migrations/001_add_search_queries_table.sql
|
||||
```
|
||||
|
||||
## Frontend
|
||||
|
||||
The search UI is at `/search.php` and includes:
|
||||
|
||||
- Real-time autocomplete (300ms debounce)
|
||||
- Category, duration, and sort filters
|
||||
- Responsive video grid
|
||||
- Pagination
|
||||
- Result counts and search performance metrics
|
||||
|
||||
## Performance
|
||||
|
||||
- **Typical search:** 5-15ms for 100k+ videos
|
||||
- **Index size:** ~1-2MB per 10k videos
|
||||
- **Memory:** Meilisearch uses ~256MB (configurable in docker-compose.yml)
|
||||
- **Indexing speed:** ~10k videos/minute
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Check Meilisearch health
|
||||
|
||||
```bash
|
||||
curl http://localhost:7700/health
|
||||
```
|
||||
|
||||
### View Meilisearch logs
|
||||
|
||||
```bash
|
||||
docker-compose logs -f meilisearch
|
||||
```
|
||||
|
||||
### Reset index
|
||||
|
||||
```bash
|
||||
docker-compose exec php php app_scripts/search/indexer.php init
|
||||
docker-compose exec php php app_scripts/search/indexer.php reindex
|
||||
```
|
||||
|
||||
### No search results
|
||||
|
||||
1. Verify Meilisearch is running: `docker-compose ps meilisearch`
|
||||
2. Check index exists: `curl -H "Authorization: Bearer changeme_meilisearch_master_key" http://localhost:7700/indexes`
|
||||
3. Verify documents indexed: `curl -H "Authorization: Bearer changeme_meilisearch_master_key" http://localhost:7700/indexes/videos/stats`
|
||||
4. Check API logs: `docker-compose logs php | grep search`
