Which results will be returned with the following Google search query? site:target.com site:Marketing.target.com accounting

This incorrectly identifies Marketing.target.com as the primary scope - the leading operator is site:target.com, making the parent domain the primary filter, not the subdomain.

Matching all words in the query does not account for the conflicting site: operator behavior - Google does not return a simple keyword union when two site: operators are specified.

Two site: operators do not produce a union of both sites - because a single page can only exist on one host, Google resolves the conflict by scoping to the parent domain and excluding the subdomain, not merging both.

When a Google query contains both `site:target.com` and `site:Marketing.target.com`, Google cannot satisfy both operators simultaneously for a single page that is not on the subdomain, so it treats the subdomain operator as an exclusion filter against the parent domain scope. The result is pages from target.com that match the keyword 'accounting' but are not located on Marketing.target.com. This behavior is used in Google hacking to refine dorking searches by excluding specific subdomains from a broader domain result set.
