Boolean search is searching with AND, OR, NOT, quotation marks and brackets to combine job titles and skills precisely. Recruiters use it on LinkedIn, job boards, ATS search and Google to find candidates who match exact criteria and to leave out those who do not.

Searching with AND, OR, NOT, quotes and brackets to combine titles and skills precisely. It works on LinkedIn, job boards, ATS search and Google.
Each operator has one job. AND narrows results by requiring every term. OR widens them by accepting any of several terms, which is how you cover different titles for the same role. NOT, or a minus sign on some sites, removes terms you do not want. Quotation marks keep a phrase together, such as “project manager”. Brackets group OR lists so the search engine reads them correctly.
A typical string looks like this: (“software engineer” OR “software developer” OR “backend engineer”) AND (Python OR Go) AND (fintech OR payments) NOT (intern OR student). Each platform supports operators slightly differently, so a string that works in one database may need tweaks in another. Combined with site search on Google, Boolean also powers X ray search of public profiles.
Why it matters to recruiters
Boolean search gives recruiters control. You decide exactly which titles, skills and terms count, and the results are predictable and repeatable. It remains the fastest way to work a large database or job board, check that an AI tool has not missed obvious candidates and build reusable searches for roles you fill often. It is a core skill for sourcers.
An example from a recruiting desk
A recruiter needs registered nurses with ICU experience in Phoenix. Her first search for nurse AND ICU returns thousands of mixed results. She rebuilds it as (“registered nurse” OR RN) AND (ICU OR “intensive care” OR “critical care”) AND Phoenix NOT (student OR LPN). In this example the list shrinks to a focused set she can review in an hour.
Tips that help
List every common title and synonym for the role before you write the string.
Put OR lists inside brackets and keep phrases in quotation marks.
Add one term at a time and watch how the result count changes.
Save strings that work so you can reuse and share them.
Mistakes to avoid
Stacking too many AND terms so the search returns almost no one.
Copying a string between platforms without checking which operators each one supports.
Which tools help?
A few of the sourcing tools in our directory. Prices are the published starting price on the date we last checked.
The main operators are AND to require terms, OR to accept any of several terms, and NOT to exclude terms. Quotation marks search an exact phrase and brackets group terms. Some sites also support a minus sign for exclusion or an asterisk as a wildcard, but support varies by platform.
Is Boolean search still useful with AI sourcing tools?
Yes. AI tools are good at finding people who describe their work in different words, but Boolean gives you exact control and predictable results. Many sourcers use AI to explore a market and Boolean to check coverage, target specific titles and search databases that do not support AI search.
Does LinkedIn support Boolean search?
LinkedIn supports Boolean operators in its search, including AND, OR, NOT, quotation marks and brackets, though features differ between free and paid products. Results are also shaped by your network and plan. Test strings and adjust them, since LinkedIn may change how searches work over time.
