-## TypeMind Plugin: EPUB/PDF/TXT Search Integration  
-
-A plugin for [TypeMind](https://docs.typingmind.com/plugins/build-a-typingmind-plugin) that mimics the **WebSearch** feature but focuses on retrieving books/documents. Users can query, e.g., *"Find me books about Hecate"*, and the plugin returns **clickable links** to relevant files (EPUB, PDF, TXT).  
-
-### Features  
-- **File Formats**: Supports EPUB, PDF, and TXT (assumed compatibility).  
-- **Requirement**: Users must provide their own files for indexing.  
-
-### Technical Context  
-- **Language**: Python.  
-- **Skill Level**:  
-  - My Python knowledge is **extremely rusty** (last project: a not too simple game bot years ago).  
-  - Self-assessment: **Python novice**.  
-- **Tools Used**:  
-  - **Sonnet 3.7** and **DeepSeek-V3-0324** (for AI/ML integration).  
-  - **RooCode** 
-
-### Purpose  
-1. **Experiment**: Test RooCode’s capabilities and identify practical applications.  
-2. **Non-Production**: **⚠️ Do NOT deploy this in production** (even if "fixed" by someone).  
-
----
-
-### Key Notes  
-- Humor/self-deprecation preserved (e.g., "extremely rusty," "novice").  
-- Technical terms standardized (Sonnet 3.7, DeepSeek-V3-0324).  
-- Critical warnings emphasized (**bold + emoji** for production risk).  
-
-
-
-# Application Deployment Guide (Ubuntu LTS)
-
-## Prerequisites
-
-### System Requirements
-- Ubuntu 22.04 LTS (64-bit)
-- Minimum 2 CPU cores, 4GB RAM
-- 20GB free disk space
-- Open ports: 8000 (app), 9200 (Elasticsearch)
-
-### Required Software
-```bash
-# Update package lists
-sudo apt update
-
-# Install Docker and Docker Compose
-sudo apt install -y docker.io docker-compose
-sudo systemctl enable --now docker
-
-# Add current user to docker group (logout required)
-sudo usermod -aG docker $USER
-```
-
-## Environment Configuration
-
-1. Clone the repository:
-```bash
-git clone https://github.com/intari/roocodetests_1.git
-cd roocodetests_1
-```
-
-2. Configure environment variables:
-```bash
-# Copy example .env file
-cp .env.example .env
-
-# Edit configuration (nano/vim)
-nano .env
-```
-Key variables to configure:
-- `BASE_URL`: Public URL of your application
-- `ELASTICSEARCH_PASSWORD`: Secure password for Elasticsearch
-- `CPU_LIMIT`: CPU cores to allocate (default: 2)
-
-## Application Deployment
-
-1. Start all services:
-```bash
-docker-compose up -d
-```
-
-2. Verify services are running:
-```bash
-docker-compose ps
-```
-
-3. Check application logs:
-```bash
-docker-compose logs -f api
-```
-
-4. Access the application:
-- Web interface: http://your-server-ip:8000
-- Elasticsearch: http://your-server-ip:9200
-
-## Maintenance
-
-## restart & rebuild
-```bash
-docker-compose down && docker-compose up -d --build
-```
-
-Logs 
-```bash
- docker logs booksearch_app  -f
-```
-
-### Log Rotation
-Configure Docker log rotation in `/etc/docker/daemon.json`:
-```json
-{
-  "log-driver": "json-file",
-  "log-opts": {
-    "max-size": "10m",
-    "max-file": "3"
-  }
-}
-```
-Then restart Docker:
-```bash
-sudo systemctl restart docker
-```
-
-### Backups
-1. Create backup script (`/usr/local/bin/backup-app.sh`):
-```bash
-#!/bin/bash
-BACKUP_DIR=/var/backups/app
-mkdir -p $BACKUP_DIR
-docker-compose exec -T elasticsearch curl -X POST "localhost:9200/_snapshot/backup_repo/_all" -H "Content-Type: application/json"
-docker-compose exec -T elasticsearch curl -X GET "localhost:9200/_snapshot/backup_repo/snapshot_$(date +%Y-%m-%d)?pretty"
-```
-
-2. Make executable and schedule daily cron job:
-```bash
-sudo chmod +x /usr/local/bin/backup-app.sh
-sudo crontab -e
-# Add: 0 3 * * * /usr/local/bin/backup-app.sh
-```
-
-### Updates
-1. Pull latest changes:
-```bash
-git pull origin main
-```
-
-2. Rebuild containers:
-```bash
-docker-compose up -d --build
-```
-
-## Troubleshooting
-
-### Common Issues
-
-**Application not starting:**
-```bash
-# Check container status
-docker ps -a
-
-# View logs
-docker-compose logs api
-```
-
-**Elasticsearch health issues:**
-```bash
-# Check cluster health
-curl -X GET "localhost:9200/_cluster/health?pretty"
-
-# Check node stats
-curl -X GET "localhost:9200/_nodes/stats?pretty"
-```
-
-**Port conflicts:**
-```bash
-# Check used ports
-sudo netstat -tulnp
-
-# Change ports in docker-compose.yml if needed
-```
-
-### Debugging
-1. Access running container shell:
-```bash
-docker-compose exec api bash
-```
-
-2. Check resource usage:
-```bash
-docker stats
-```
-
-## Check Request via JSON :
-curl -H "Accept: application/json" -X GET https://booksearch.yourdomain.com/search?query=android
-
-# Simple search
-curl -H "Accept: application/json" "https://booksearch.yourdomain.com/search?query=android"
-
-# Search with format parameter
-curl "https://booksearch.yourdomain.com/search?query=android&format=json"
-
-# Error case
-curl -H "Accept: application/json" "https://booksearch.yourdomain.com/search"
-
-
-## API Endpoints
-
-### Search API
-```
-GET /search?query={query}[&format=json]
-```
-
-### Reset Elasticsearch Index
-```
-POST /reset_index
-Headers:
-- Authorization: Basic base64(username:password)
-```
-
-Example:
-```bash
-curl -X POST -u admin:securepassword123 https://booksearch.yourdomain.com/reset_index
-```
