The People Search Engine doesn't return 5,000 results: it returns a **shortlist of the 25 best people** for your query. ## How it works 1. It first searches **inside Cobalt** (your pool) — for example candidates who could match a need, or prospects who might be interested in meeting a candidate. 2. It then complements this with an **external search** covering everyone with **more than 100 LinkedIn connections** — useful to find new candidates or new prospects. People Search Engine results list with scores ## Filters Refine your searches with the **filters** available on the results — for example location, availability, seniority, or contract type. People Search Engine filters ## Customizable columns Each user can **customize the columns shown** in the results, at their own level — without affecting the display for other team members. Column customization at the user level ## Relevance score Each profile shows a **score** for your query, along with an **explanation** of what makes the profile relevant. A profile's relevance score with its explanation ## Profile details Click a profile to access more information: **past experience, education, and skills**. You can also **enrich the phone and email** (work and/or personal) — see [Enrichment](/en/fonctionnalites/enrichissement) to learn more. Profile details with experience and contact info If the candidate is **already in the CRM**, you'll find their **documents** directly — CV, skills documents, and so on. Documents of a candidate already in the CRM ## Add to the CRM or a project From a profile, add the person directly to the **CRM**, or to a **project** — existing or new if it doesn't exist yet (see [Projects](/en/fonctionnalites/projets/overview) to learn more). Add a profile to an existing or new project You can add them **one by one** (to different projects or the same one), or **select several — or all** — to add them to a project at once. Multi-selecting profiles to add to a project You can also **enrich all phones and emails** before adding them to projects — or do it afterwards, as needed.
