Finding great talent isn’t easy, especially for technical roles. Most recruiters spend about a third of their workweek just searching for the right candidates to contact.
If you’re looking to source candidates faster and more effectively, one of our favorite techniques is Boolean Search.
We put together this comprehensive Boolean search strings cheat sheet with Boolean operator explanations, specific search strings for the most popular technical roles, advanced techniques for recruiters, diversity searching, and a Boolean operator FAQ.

What are Boolean Search Strings and Boolean Operators?
Boolean search was first developed in the 19th century as a method of symbolic logic. In the present day, it is a type of search that allows users to combine keywords and Boolean operators (AND, OR, and NOT) to create more targeted and accurate searches.
A Boolean search string combines keywords or an exact phrase, and Boolean operators to find specific information from a search engine that wouldn’t be available by just typing in a single keyword.
What is Boolean search in recruitment?
Sourcers and recruiters can save time and find candidates with the right skills more quickly by creating boolean search strings with relevant keywords and operators in Google or any search engine.
Here are the Boolean operators recruiters will find most helpful when searching for technical talent, with explanations and examples.
|Boolean Operator||Boolean Operator Use||Example Boolean Search Strings|
|AND||For locating resources that contain two or more keywords||Developer AND Python|
|OR||For locating resources that contain at least one of a list of two or more keywords||Developer OR Engineer OR programmer|
|NOT-||Excludes resources that contain a keyword||Python NOT snake|
|“ ”(quotation marks)||For locating resources that contain an exact phrase||“Data Infrastructure Engineer”|
|site:||For located resources on a particular website||Blockchain software engineer site:twitter.com|
|inurl:||For locating resources that contain (a) keyword(s) in the url||inurl:resume|
|*||For searching with unknown characters or words||develop*|
(returns developer, developed, development…)
|( )||For creating more complex searches and nesting search terms||(Python OR Ruby OR Node OR Go) AND (React OR Angular OR Vue)|

Helpful tips for building better Boolean search strings
Mastered all the Boolean search terms and basic techniques? Here are some recruiting-specific tips and tricks for finding the best technical talent with Boolean strings.
Use your Boolean Strings in creative talent pools
Beyond resume databases and career pages, Boolean search can be used on many other types of platforms. In particular, recruiters should consider that:
Many software engineers who don’t market themselves on career sites can be found in online communities such as GitHub, the most popular place for maintaining code, and Stack Overflow, another popular gathering spot for discussing all things tech.
Social media websites such as Twitter and Discord are also great places to connect with software developers and engineers who are staying on top of the newest trends, learning new technologies and tackling complex projects outside of their day job.
Your Applicant Tracking System (ATS) is also a great place to search for relevant candidates you have previously contacted. Perhaps it just wasn’t the right time for a candidate to make a move, but now it is. Or, perhaps a candidate wasn’t a good fit for a previous role, but they are a great fit for a current role.
Use Boolean search parameters to target the right seniority level
When it comes to software engineering titles, there is a good deal of overlap and variance. Some companies call their developers “Software Engineer,” and others use “Software Development Engineer” (SDE) or “Member of Technical Staff” (MTS).
Another way in which titles vary from company to company is specificity. A backend developer, cloud engineer, and data engineer might all call themselves a “Software Engineer” on their online profile. Using as many variations of a title as possible will help you to ensure you aren’t overlooking potential candidates.
Once you’ve located profiles that could be a fit through Boolean search and a Boolean operator, consulting a resource like levels.fyi can help you to interpret what a given title at a given company might actually mean. For example, a Senior Software Engineer at Google could be a good fit for a Software Engineer V role at Facebook.
On the other hand, company selectivity also matters. A “Senior Software Engineer” at a small startup might join a highly selective company such as Google at a lower level.
Experiment and practice to develop your Boolean searching intuition
While different websites such as Google, LinkedIn, GitHub, and Twitter all support Boolean searching, each platform has its own quirks and variations. For example, some search engines may correct misspelled keywords or automatically include variants, and others may not. The Boolean operator that is supported and the details of how each Boolean search term functions may also morph over time due to updates on each platform.
While you can check the help documentation for the specific search engine you’re using, ultimately, hands-on experience will give you an intuitive understanding of the most productive ways to combine Boolean operators and keywords and what you can expect to find through a Boolean string.
Boolean Searching FAQ:
Here are some quick answers to common Boolean Search, Boolean Operator, and Boolean String questions.
Is a Boolean search operator case-sensitive?
A Boolean operator (AND, NOT, OR) is case-sensitive. However, keywords are not case-sensitive.
That means that “Python AND Spark” differ from “Python and Spark.”
However, “Python AND Spark” is the same as “python AND spark,”
What is the difference between Boolean Searching and Advanced Search?
Boolean search and advanced search are both used to refine and narrow down search results, but they work in different ways.
Boolean search allows users to specify the relationships between different terms in the search query, by using a Boolean operator to combine keywords. A Boolean string can be used in all different kinds of search engines to generate search results.
Advanced search, on the other hand, uses filters (date, file type, location…) and search criteria (“all of these words,” “exact phrase,” “none of these words,” “only results”) to generate a search result. It is generally a feature provided by the specific search engine being used and varies from engine to engine.
How do I find diverse talent with Boolean search?
Here are some ideas for building Boolean search strings to target diverse talent.
- Women’s colleges, Historically Black Colleges and Universities (HBCUs), and traditionally Native American colleges
- Sororities and fraternities for Black, Hispanic/Latino/a/x, and Asian & Pacific Islander students
- Female first names
- Women’s organizations, African-American organizations, Hispanic/Latino/a/x organizations, Asian-American organizations, Native American organizations, LGBTQ organizations, and organizations for Americans with disabilities
Example Boolean search string abbreviations and Boolean operator:
Techlatino OR “Latinas in tech” OR “Hispanic foundation of silicon valley” OR hfsv OR lulac OR “league of united Latin American citizens” OR “Hispanic IT executive council” OR “society of Hispanic professional engineers” OR shpe
