Question 1

How to filter archived files by MIME type using GoGetCrawl CLI?

Accepted Answer

Use the -f flag with the 'mimetype:' prefix, e.g., 'gogetcrawl download *.cia.gov/* -f mimetype:application/pdf' to download only PDF files, as shown in the README download example. This allows precise targeting of specific content types from archives.

Question 2

GoGetCrawl vs. using Common Crawl's AWS tools directly: which is better?

Accepted Answer

GoGetCrawl abstracts the complexity of querying Common Crawl's indexes and Wayback Machine's CDX server, providing a simpler, unified interface for developers. However, direct AWS tools offer more granular control and customization for advanced, large-scale data engineering tasks.

Question 3

Can I use GoGetCrawl to scrape live websites?

Accepted Answer

No, GoGetCrawl is designed specifically for historical web archives like Common Crawl and Wayback Machine, not for real-time scraping. For live websites, consider tools like Colly or Scrapy that handle dynamic content and anti-bot measures.

Question 4

How to handle concurrent requests in the Go package?

Accepted Answer

Use concurrent methods like FetchPages for CommonCrawl, which return results via channels, as demonstrated in the concurrent usage example. This enables efficient parallel processing but requires manual channel management for error handling.

Question 5

Is GoGetCrawl suitable for downloading large volumes of archived data?

Accepted Answer

Yes, with configurable workers and filters, it can handle large datasets efficiently. However, users should monitor resource usage, as it lacks built-in throttling or resume capabilities for interrupted downloads.

Question 6

Does GoGetCrawl support wildcard domains in queries?

Accepted Answer

Yes, wildcards are supported in URL patterns, e.g., '*.example.com/*' to match any subdomain and path, as used in CLI examples for fetching URLs from multiple domains or specific paths.
