AddSearch allows for adding multiple domains to your account. You can add top-level domains (yourotherwebsite.com) and subdomains (subdomain.yoursite.com) for indexing on your account.
The domains added for indexing share the same search index and can be searched with any of AddSearch’s search views. AddSearch returns search results from all the domains by default but you can filter search results based on a domain name.
Multiple domain support is useful when you have content on many websites and want to have single-point access to the content from all the domains.
To add domains to your account, follow these instructions:
AddSearch crawls the pages from the new domain to the index automatically.
By default, AddSearch returns search results from all your domains. To receive results from a single domain you need to use category filters. To use these filters, your installation script needs an additional “categories” parameter with a 0x prefixed domain filter:
You can add multiple categories by separating them with a comma. If the value of categories parameter is 0xblog.domain.com,0xwww.domain.com, you will see results from blog.domain.com and www.domain.com.
