Boolean Search Mastery: Beyond the Basics

Your LinkedIn Recruiter search just returned 847 results. You scroll through page after page of irrelevant profiles. Software engineers who barely touched Python. Senior people when you need junior. People in the wrong locations. After an hour, you've found maybe 3 decent candidates.

Sound familiar?

Meanwhile, the recruiter at your competitor types in a search string, gets 23 highly targeted results, and finds 5 perfect candidates in 10 minutes.

The difference? They know Boolean search. You don't.

After teaching Boolean search to 500+ recruiters and analyzing what actually works, we've identified the exact techniques that separate amateurs from experts.

Why Most Recruiters Suck at Boolean Search

The problem isn't that Boolean is hard. It's that most people never learned it properly.

What you probably know:

• AND = both terms must appear
• OR = either term can appear
• NOT = exclude this term

What you probably don't know:

• How to combine operators strategically
• When to use quotes vs. parentheses
• Platform-specific syntax differences
• How to search for titles vs. skills vs. companies
• Advanced proximity operators
• How to exclude false positives systematically

The result? You waste hours getting mediocre results while thinking "Boolean doesn't work."

Boolean Basics (Quick Refresher)

The Three Core Operators

AND - Both terms must appear

Example: "software engineer" AND python

Returns: Profiles with both "software engineer" AND "python"

OR - Either term can appear

Example: developer OR engineer OR programmer

Returns: Profiles with any of these terms

NOT - Exclude this term

Example: engineer NOT intern

Returns: Engineers but excludes interns

The Critical Fourth Operator: Parentheses

This is where amateurs fail.

Parentheses control the order of operations, just like math.

Bad search:

software engineer OR developer AND python

Ambiguous. Unclear what matches what.

Good search:

(software engineer OR developer) AND python

Clear: Must have python, plus either "software engineer" OR "developer"

Rule: Always use parentheses to group OR statements.

Advanced Boolean Techniques That Actually Work

Technique #1: The Multi-Tier Title Search

Problem: People use different titles for the same role.

Amateur search: "software engineer"

Misses: Developer, Programmer, SWE, Software Dev, etc.

Expert search: (title:"Software Engineer" OR title:"Software Developer" OR title:"Developer" OR title:"SWE" OR title:Programmer) AND python

Pro tip: List 8-12 title variations for best results.

Technique #2: Skills Clustering

Problem: Skills appear in different formats.

Amateur search: react

Matches: Someone who "reacted" to something in their profile

Expert search: (React OR ReactJS OR "React.js" OR "React Native") AND ("front end" OR "front-end" OR frontend)

Why it works: Captures all variations + confirms it's actual front-end work.

Technique #3: The Exclusion Strategy

Problem: False positives waste time.

Amateur search: manager AND recruiting

Returns: Recruiting managers (good) + people who mentioned recruiting once (bad)

Expert search: title:(manager OR director OR "head of") AND (recruiting OR "talent acquisition" OR "people operations") NOT (intern OR coordinator OR assistant OR associate OR recruiter)

The key: Systematically exclude junior levels and non-manager roles.

Technique #4: Company Targeting

Problem: You want people from specific companies or company types.

Expert search for FAANG experience:

(company:Google OR company:Facebook OR company:"Meta" OR company:Amazon OR company:Apple OR company:Netflix) AND (title:"Senior Engineer" OR title:"Staff Engineer")

Expert search for startup experience:

("Series A" OR "Series B" OR "seed funded" OR "YC" OR "Y Combinator") AND (title:founder OR title:"founding engineer" OR title:"early engineer")

Technique #5: Skills Combination Search

Problem: You need specific skill combinations.

Expert search for full-stack engineer:

(React OR Vue OR Angular) AND (Node OR "Node.js" OR Express) AND (MongoDB OR PostgreSQL OR MySQL) AND (title:engineer OR title:developer)

Why it works: Ensures they've actually done both front-end AND back-end.

Technique #6: Geographic Precision

Problem: Location fields are messy.

Amateur search: location:"New York"

Misses: NYC, Manhattan, Brooklyn, etc.

Expert search: (location:"New York" OR location:NYC OR location:Manhattan OR location:Brooklyn OR location:Queens OR location:"Bronx" OR location:"Staten Island" OR postal:10*)

Pro tip: Use postal codes with wildcards for coverage.

Technique #7: Education Targeting

When you need specific backgrounds:

For CS degrees: ("Computer Science" OR "Computer Engineering" OR "Software Engineering") AND (school:MIT OR school:Stanford OR school:"Carnegie Mellon" OR school:"UC Berkeley")

For bootcamp grads: (bootcamp OR "coding bootcamp" OR "General Assembly" OR "Hack Reactor" OR "Flatiron" OR "App Academy")

Technique #8: Experience Level Indicators

Problem: "Senior" appears in random places.

Amateur search: senior AND engineer

Returns: Anyone who mentioned "senior" anywhere

Expert search: title:(Senior OR Staff OR Principal OR Lead) AND engineer AND NOT (intern OR junior OR associate OR "entry level")

Platform-Specific Boolean Syntax

LinkedIn Recruiter

Special operators:

• title: = Search only job titles
• company: = Search only company names
• school: = Search only schools
• location: = Search only locations

Example: title:("Software Engineer" OR Developer) AND company:(Google OR Facebook) AND location:"San Francisco Bay Area"

LinkedIn quirks:

• Use quotes for multi-word phrases
• Case doesn't matter
• Parentheses are critical

GitHub Search

Special operators:

• language: = Programming language
• stars: = Minimum stars
• followers: = Minimum followers

Example: language:python stars:>100 followers:>50

For finding engineers by project: ("machine learning" OR "deep learning") language:python stars:>10 in:readme

Twitter/X Advanced Search

For finding thought leaders: (AI OR "artificial intelligence" OR "machine learning") AND (min_retweets:100) -filter:replies

Google X-Ray Search

For finding profiles on any site:

LinkedIn profiles: site:linkedin.com/in/ "software engineer" python "San Francisco"

GitHub profiles: site:github.com "machine learning" location:"New York"

AngelList profiles: site:angel.co founder "Series A" "San Francisco"

Boolean Search Templates by Role

Software Engineer (Mid-Level)

(title:"Software Engineer" OR title:"Developer" OR title:"Programmer" OR title:"SWE") AND (python OR java OR javascript OR "C++" OR golang) AND NOT (intern OR junior OR entry OR associate OR "entry level" OR student) AND (years:"3" OR years:"4" OR years:"5" OR "3 years" OR "4 years" OR "5 years")

Data Scientist

(title:"Data Scientist" OR title:"ML Engineer" OR title:"Machine Learning") AND (python OR R OR "machine learning" OR "deep learning" OR TensorFlow OR PyTorch) AND ("PhD" OR "Master's" OR "bachelor's") AND NOT (intern OR junior OR student)

Product Manager

(title:"Product Manager" OR title:"PM" OR title:"Product Lead") AND (agile OR scrum OR roadmap OR "product strategy" OR "user research") AND (company:"tech startup" OR company:Google OR company:Facebook OR company:Amazon OR company:Microsoft) AND NOT (associate OR intern OR coordinator)

Sales Executive

(title:"Sales Director" OR title:"VP Sales" OR title:"Head of Sales" OR title:"Chief Revenue Officer" OR title:CRO) AND (SaaS OR "software sales" OR "enterprise sales" OR B2B) AND ("quota attainment" OR "revenue growth" OR "team leadership") AND (years:"5+" OR years:"10+" OR "5+ years" OR "10+ years")

Marketing Manager (Digital)

(title:"Marketing Manager" OR title:"Digital Marketing" OR title:"Growth Marketing") AND (SEO OR SEM OR "content marketing" OR "social media" OR "email marketing") AND (Google Analytics OR HubSpot OR Marketo OR Salesforce) AND NOT (intern OR associate OR coordinator)

Common Boolean Mistakes to Avoid

Mistake #1: Not Using Quotes for Phrases

Wrong: software engineer (Matches: Anyone with "software" OR "engineer" anywhere)

Right: "software engineer" (Matches: Only the exact phrase)

Mistake #2: Forgetting Parentheses with OR

Wrong: engineer OR developer AND python (Unclear logic, unpredictable results)

Right: (engineer OR developer) AND python (Clear: Must have python + one of the titles)

Mistake #3: Too Broad Exclusions

Wrong: engineer NOT manager (Excludes: Everyone with "manager" anywhere including "project manager" experience)

Right: engineer NOT title:manager (Excludes: Only people whose current title is manager)

Mistake #4: Not Testing Incrementally

Wrong approach: Build massive 20-line search, run it, get 0 results, give up

Right approach:

1. Start simple: "software engineer"
2. Add language: "software engineer" AND python
3. Add location: Previous + location:"San Francisco"
4. Add exclusions: Previous + NOT intern
5. Refine until results are targeted

Mistake #5: Ignoring Synonyms

Wrong: "full stack engineer" (Misses: "Full-stack", "Fullstack", "Full Stack Developer")

Right: ("full stack" OR "full-stack" OR fullstack OR "full stack developer")

Power User Techniques

Technique #1: Stacking Searches

For comprehensive coverage:

Search 1: Current employees at target companies

(company:Google OR company:Facebook) AND title:"Software Engineer"

Search 2: Former employees now available

(past-company:Google OR past-company:Facebook) AND title:"Software Engineer" AND NOT (company:Google OR company:Facebook)

Search 3: People with target company experience + startup interest

(past-company:Google OR past-company:Facebook) AND (startup OR "early stage" OR "Series A")

Technique #2: The Inverse Search

Find people like your best performers:

1. Analyze your top employee's profile
2. Extract: Schools, past companies, skills, title progression
3. Build search matching that pattern

Example: (school:Stanford OR school:MIT) AND (past-company:Google OR past-company:Amazon) AND (python OR java) AND title:"Software Engineer" AND years:"3-5"

Technique #3: The Competitive Intelligence Search

Find who's hiring similar roles: "we are hiring" AND "software engineer" AND (company:"competitor 1" OR company:"competitor 2")

Then reach out to people applying there.

Technique #4: The Content Creator Search

Find industry thought leaders: (author OR speaker OR "conference speaker" OR blogger OR "thought leader") AND ("machine learning" OR "artificial intelligence") AND (published OR "blog post" OR article OR book)
