The Recruiter's Complete Boolean Search Guide: Strings That Actually Work in 2025
Boolean search isn't dead—it's just evolved. Here's how to build strings that still pull real candidates from LinkedIn, Google, and your ATS.
Everyone's talking about AI sourcing. But here's the thing: AI still needs good inputs. And nothing gives you more control than a well-built Boolean string.
The basics haven't changed. AND narrows. OR broadens. NOT excludes. Quotation marks lock in exact phrases. Parentheses group logic. But the platforms have. LinkedIn's search has gotten stingier with what it exposes to crawlers. Google X-Ray—searching LinkedIn via Google—still works, but you need to know the operators that actually return results.
For LinkedIn Recruiter, keep it tight. Too many ORs and you'll get noise. Too many ANDs and you'll get nothing. A solid pattern: (title OR "job title") AND (skill1 OR skill2) AND location. Use the minus sign for NOT. And remember—LinkedIn truncates, so put your most important terms first.
For Google X-Ray, you're adding site:linkedin.com/in to force results from LinkedIn profiles. Combine that with intitle: for keywords in the headline, or inurl: for terms in the profile URL. Recruiters who nail this report 45% faster time-to-fill and way larger candidate pools than those who don't.
The real skill is iteration. Start broad, then narrow. If you get 500 results, add a NOT. If you get 5, drop an AND. Build a library of strings for your most common roles—and tweak them as the market shifts.
