As of today, certain job-related search-queries will yield job postings culled from different job boards — and they'll show up right in your search results. Those postings will be augmented, in some cases, by the time it would take to commute from your house and by the employer's ratings on sites like Glassdoor.
Why it matters: The project is part of a larger initiative called Google for Jobs that the company talked about at its annual Google I/O conference. It's also part of a larger trend of Google putting information directly in search results in an attempt to help people get more information without leaving Google's site.
