Boolean Search for Recruiters: A Beginner's Guide

Boolean search is a way of combining words with the operators AND, OR and NOT so a search engine returns only the profiles that fit. AND narrows a search, OR widens it, NOT removes unwanted results, and quotation marks and brackets control how the words are grouped. Once you know those five tools you can build a precise search for almost any role.

What do AND, OR and NOT actually do?

AND requires both terms: "python AND django" returns profiles that mention both. OR accepts either: "developer OR engineer" catches both job titles. NOT excludes a term: "engineer NOT manager" drops anyone whose profile contains the word manager. Most search tools expect the operators in capital letters.

Why do quotation marks and brackets matter?

Quotation marks keep a phrase together, so "project manager" is searched as one title instead of the words project and manager anywhere in the profile. Brackets group terms so the operators work as you intend: (developer OR engineer) AND (python OR java) means one of the first group and one of the second. Without brackets, the order in which the engine reads the operators can give surprising results.

How do I build a search string step by step?

Work in layers. First, list the job title and its common variations, joined with OR inside brackets. Second, add the must-have skills, joined with AND, with synonyms joined by OR in their own brackets. Third, add a location. Fourth, add NOT terms for results you do not want, such as a seniority level or the word intern. Finally, run it and read the first page of results; if they are off, loosen or tighten one layer at a time.

What is an example string?

For an example role of a data analyst in Manchester, a string could be: ("data analyst" OR "business analyst" OR "reporting analyst") AND (SQL OR Python) AND (Tableau OR "Power BI") AND Manchester NOT intern. This is an illustration, not a rule, so adjust the titles and tools to the real job.

What mistakes return the wrong people?

The usual causes are too many AND terms, which leaves almost no results, a title without its variations, which misses people whose employer uses a different name for the job, and missing brackets. Another is treating a search as finished after one try. Good sourcers adjust the string several times.

Where can I use Boolean strings?

Applicant tracking systems, job boards, LinkedIn and Google all accept some form of Boolean, though each has its own limits and syntax details, so check the tool you use. If you would rather not type operators by hand, the Rezumz Boolean Search Builder turns titles, skills and a location into a ready string for LinkedIn and Google, with title variations added.
