Site Search Crawler Overview
The easiest way to get started is to let the Site Search Crawler 'crawl' your content.
A crawler, or web crawler, is a robust application which scans the content of webpages.
Our Swiftbot is a high-performance web crawler that will quickly crawl and index your webpages.

What is a Crawler-based Engine?
There are two possible Engine types within Site Search:
If you use the crawler, then you have a Crawler-based Engine.
If your Engine was created as an API-based Engine during your initial signup or created via the Engines API, then it is an API-based Engine - you will know if that was the case!
If you are unsure, assume you are using a Crawler-based Engine.
By default, the crawler will crawl each available page within your domain.
In many cases, you will want to specify what will be crawled, what will be indexed, and more.
To control how your content is indexed, you might apply:
- Dashboard: Manage Crawl Rules
- Meta Tags
- Content Curation Rules.
- robots.txt Files
- sitemap.xml Files
- RSS or Atom Feeds
For the full list of tools at your finger tips, see Crawler Configuration.
Crawling Multiple Domains
The crawler will not cross domains while indexing content -- including subdomains!
To index multiple domains...
- Add them when first creating the Engine
- Add them via the Manage Domains page on the Dashboard.
- (Optional) Use the Crawler Operations API endpoint.
For more information on multilpe domains, see the multiple domains guide.
Site Search will re-index your content periodically.
You can force a re-crawl by clicking the Recrawl button on the Domains page of the dashboard.
Or, you can use the Crawler Operations API endpoint.
Crawler API Control
Crawler-based Engines can be controlled through a variety of robust and useful API endpoints.
There is one key difference...
A Crawler-based Engine indexes documents via the Crawler. API-based Engines index via the API.

Default Page Schema
When your pages are crawled, the content is indexed according to a schema.
When a page is indexed a default DocumentType called
page is created:
||No.||For crawler based search engines, the hexadecimal MD5 digest of the normalized URL of the page.|
