Limit Amazon Q web crawler to single domain

Question

How can I configure an Amazon Q web crawler to index only the single domain that I specify?

I have set it to "Sync domains only". Using a source url like site.example.com. I only want to index pages like https://site.example.com/* (and https://www.site.example.com/*)

The site.example.com page includes links to urls like https://example.com/page and https://other.example.com/page, and I do not want to crawl or index those pages.
However, I see those pages being crawled and indexed in the logs and it just crawls out all over the example.com domain. I have crawl depth set to 6 because out site is fairly deep.

Adding a URL Crawl Inclusion pattern like https://site.example.com/.* fails to crawl any pages.

Thanks!

Hi Shayne.

Although I have not tried this scenario, a couple of possible options are:
1. Use Sitemap. Per the [documentation](https://docs.aws.amazon.com/amazonq/latest/business-use-dg/webcrawler-console.html): 
> If you want to crawl a sitemap, check that the base or root URL is the same as the URLs listed on your sitemap page. For example, if your sitemap URL is https://example.com/sitemap-page.html, the URLs listed on this sitemap page should also use the base URL "https://example.com/".
2. Include/Exclude explicitly using robots.txt. From the [documentation](https://docs.aws.amazon.com/amazonq/latest/business-use-dg/stop-web-crawler.html): 
> Amazon Q Web Crawler respects standard robots.txt directives like Allow and Disallow. You can modify the robot.txt file of your website to control how Amazon Q Web Crawler crawls your website.
> Use the user-agent to make entries designed for Amazon Q. `User-agent: amazon-QBusiness`

I hope this helps.

You need to use a regular expression to only crawl the domain you're interested in. That way, the crawler would ignore the pages outside the domain you want to crawl.

This [blog](https://aws.amazon.com/blogs/machine-learning/index-website-contents-using-the-amazon-q-web-crawler-connector-for-amazon-q-business/) post has a couple of examples.
