Boolean library

    Boolean search strings for every role and platform

    Copy-paste Boolean search strings for LinkedIn, GitHub, Stack Overflow, X and Google X-Ray, tuned for 30+ recruiting roles.

    Boolean search is still the fastest way to find passive candidates who never apply. The right string surfaces 10× more relevant profiles than a basic keyword search — but writing one well takes practice.

    This library gives you copy-paste-ready Boolean strings for every major sourcing platform, tuned per role. Pick a role below to see the full string set, including platform-specific variants and exclusion terms.

    Frequently asked questions

    Are these strings actually tested?

    Yes — each string is hand-crafted by a sourcing specialist and tested against current 2026 platform behaviour (LinkedIn Recruiter syntax changed materially in late 2025).

    Can I use these on the free LinkedIn search?

    Yes — every LinkedIn string is written for the free version of LinkedIn search. Recruiter-licence-only operators are flagged separately.

    How often is the library refreshed?

    Quarterly, plus immediate updates when LinkedIn, GitHub or Google change their search syntax materially.
