The complete Boolean search strings cheat sheet for tech recruiters (2026)

Boolean search remains the highest-ROI skill for tech recruiters. While AI sourcing algorithms continue to evolve, Boolean operators give recruiters surgical control over exact must-have qualifications, licensing, and titles without paying for unlimited enterprise seats.

Core Boolean operators refresher

• AND: Requires all terms to appear (e.g. `Java AND "Spring Boot"`). Narrowing operator.
• OR: Broadens results by searching synonyms and framework variants (e.g. `React OR ReactJS OR "React.js"`).
• NOT / minus (-): Eliminates false positives and job postings (e.g. `-recruiter -jobs -hiring`).
• Quotation marks (""): Enforces exact phrase matching (e.g. `"Full Stack Developer"` vs separate words).
• Parentheses (): Controls logic precedence and execution order when grouping synonyms.

Google X-Ray syntax for LinkedIn profiles

When your commercial search limit on LinkedIn is capped, Google X-Ray lets you query public profiles directly. The universal formula: `site:linkedin.com/in/ ("Job Title") ("Primary Skill") ("Secondary Skill") -job -jobs -recruiter`. See our guide on LinkedIn Recruiter vs Google X-Ray for deeper comparison.
