URL domain filters

We've added new domain-based filters to both Jobs Search endpoint and Company Search endpoint:

New filters:

• url_domain_or - Find jobs/companies from specific domains
• url_domain_not - Exclude jobs/companies from specific domains

This allows you to target or exclude jobs from specific platforms like greenhouse.io, workable.com, linkedin.com, etc. Perfect for focusing on direct company postings or excluding certain job boards from your results.
