What it is
Boolean search applies the logic operators AND, OR and NOT to a candidate database such as LinkedIn or a CV store. AND narrows ("Python AND Kubernetes"), OR broadens ("VP OR Head OR Director"), and NOT excludes ("engineer NOT manager"). Combined with quotation marks and brackets, these operators turn a vague search into a precise one.
The technique is decades old and still indispensable. A good Boolean string is the difference between scrolling through thousands of loosely relevant profiles and landing on the few dozen people who genuinely match a niche brief.

Why it matters
Sourcing speed is a competitive edge. When a client gives you a brief, the agency that puts the right names on the table the same day usually wins the work. Boolean search is what makes that speed possible for hard, specific roles where keyword search alone returns noise.
It also enforces rigour. By forcing you to articulate exactly which skills, titles and exclusions define the role, a Boolean string makes your sourcing repeatable and reviewable, rather than a series of one-off guesses that nobody else could reproduce.
How boilr handles it
boilr is a sales employee first, focused on winning the brief, but the two motions connect. When the agent works an account, the role criteria it gathers are the same criteria that drive precise candidate sourcing, so the search is framed from the outset rather than reverse-engineered later.
Where boilr sources candidates for an open role, it applies the same logic a strong Boolean string encodes, matching exact skills, titles and exclusions, and it remembers what worked in the Company Brain. The strings and shortlists that fill a niche role once become reusable knowledge for the next one, instead of being rebuilt from scratch.
