🧠 Advanced Techniques

Using as a Library

package main

import (
    "context"
    "fmt"
    "time"
    
    "github.com/RahulSDevloper/Search-Engine-Scraper---Golang/pkg/engines"
    "github.com/RahulSDevloper/Search-Engine-Scraper---Golang/pkg/models"
)

func main() {
    // Create a new Google search engine
    engine := engines.NewGoogleSearchEngine()
    
    // Configure search request with optimization strategy
    request := models.SearchRequest{
        Query:       "golang concurrency patterns",
        MaxResults:  10,
        Timeout:     30 * time.Second,
        UseHeadless: true,
        Debug:       true,
    }
    
    // Execute search with context for cancellation
    ctx, cancel := context.WithTimeout(context.Background(), 45*time.Second)
    defer cancel()
    
    results, err := engine.Search(ctx, request)
    if err != nil {
        fmt.Printf("Error: %v\n", err)
        return
    }
    
    // Process and analyze results
    for i, result := range results {
        fmt.Printf("%d. %s\n%s\n\n", i+1, result.Title, result.URL)
    }
}

Custom Rate Limiting

# ~/.config/gosearch/config.yaml
rate_limits:
  google: 10   # requests per minute
  bing: 15
  duckduckgo: 20

proxy_rotation:
  enabled: true
  proxies:
    - http://proxy1:8080
    - http://proxy2:8080
  rotation_strategy: round-robin  # or random

🐞 Debugging

No Results Found?

If you're not getting any results, try these solutions:

1. Use Headless Mode to avoid detection

   ./gosearch --query "your search" --headless

2. Use a Proxy to route through a clean IP address

   ./gosearch --query "your search" --proxy http://your-proxy-server:port

3. Enable Debug Mode to examine the HTML response

   ./gosearch --query "your search" --debug

Debugging Process Flow

graph TD

    B -->|No| D[Enable Debug Mode]
    D --> E[Check HTML Responses]
    E --> F{Captcha Present?}
    F -->|Yes| G[Use Headless + Proxy]
    F -->|No| H[Check Selectors]
    H --> I[Update Selectors]
