LinkedIn has updated its search functionality across different account types. For basic free accounts, users will now be limited to searching by city instead of zip code, see only 10 search results per page with minimal profile information, and have a maximum of 50 profile views. Premium accounts maintain more advanced search features like Boolean operators and job title searches. While some information is hidden on basic profiles, using an external site search like Google can still reveal full LinkedIn profile details through XRay searches. Overall, the updates shift more advanced search features to paid account levels.
