LinkedIn X-Ray Search in 2023: The Ultimate Guide to Boolean Recruiting

LinkedIn Boolean search allows recruiters to go beyond basic keywords and leverage advanced operators to uncover highly targeted candidate profiles. Known as “X-Ray search”, these techniques can help you tap into LinkedIn’s hidden talent pool.

In this comprehensive guide, we’ll explore everything you need to know about LinkedIn XRay search in 2023 – from basic Boolean strings to advanced sourcing tactics.

Introduction to LinkedIn X-Ray Search

LinkedIn X-Ray search refers to utilizing Boolean search operators and advanced keywords to uncover “hidden” candidate profiles on LinkedIn.

It provides recruiters a way to go deeper than surface-level searches and tap into LinkedIn’s 500+ million members to identify qualified, interested talent that fits specific criteria.

Here’s a quick overview of how LinkedIn X-Ray search works:

• Boolean Operators – AND, OR, NOT, and parentheses group keywords logically
• Advanced Syntax – Quotes, wildcards, ranges, and proximity target results
• Keyword Selection – Specific job titles, skills, employers, and schools optimize targeting
• Customization – Build tailored searches for ideal candidate parameters
• Segmentation – Isolate niche groups and connections within large pools

Unlike simple searches on Google, mastering this syntax and a strategic sourcing approach allows recruiters to deliver highly targeted, nuanced results.

In this guide, we’ll explore real examples and best practices for executing advanced Boolean searches on LinkedIn and leveraging X-Ray recruiting techniques in your sourcing.

LinkedIn X-Ray Search vs Basic Keyword Search

To understand the power of LinkedIn X-Ray, it helps to first contrast it with a basic keyword search:

Basic LinkedIn Keyword Search

• Uses one or two isolated terms like “sales manager”
• Returns broad, vague results
• Requires manual filtering and vetting
• Misses qualified candidates due to limited criteria
• Struggles with common titles and names
• Fails to segment within large result sets

LinkedIn X-Ray Boolean Search

• Utilizes precise Boolean strings with multiple operators
• Returns ultra-targeted, specific profiles
• Surfaces “hidden” candidates that avoided basic keywords
• Applies multiple filters and custom criteria in one search
• Uncovers “diamonds in the rough” with niche skills
• Easily segments AnyWHERE term appears in profile

As you can see, LinkedIn X-Ray recruiting leverages search syntax and strategy to deliver results tailored to your ideal candidate parameters. Next, let’s break down the key operators.

Core Boolean Operators for LinkedIn X-Ray Search

Here are the four essential Boolean operators for constructing X-Ray search strings on LinkedIn:

AND – Requires both terms on either side

• Example: product manager AND San Francisco
• Returns profiles with BOTH “product manager” AND “San Francisco”

OR – Returns results matching either term

• Example: marketing OR advertising
• Returns profiles with EITHER “marketing” OR “advertising”

NOT – Omits results containing term after NOT

• Example: programmer NOT junior
• Returns programmers excluding profiles with “junior”

Quotation Marks “” – Groups exact phrase match

• Example: “machine learning”
• Returns profiles containing the exact phrase “machine learning”

Mastering these four operators provides immense power to craft targeted X-ray searches. But additional syntax takes it even further.

Advanced X-Ray Search Syntax and Operators

Beyond the core operators, here are some advanced Boolean syntaxes for incredibly precise LinkedIn searches:

Wildcard * – Matches any number of characters

• Example: account*
• Matches “accounting”, “accountant”, “accountable” etc.

Proximity ~ – Terms within x words of each other

• Example: “project manager” ~5 developer
• Returns profiles with the developer within 5 words of “project manager”

Site: – Only returns results from a specific domain

• Example: accountant site:wellsfargo.com
• Only surfaces accountants at Wells Fargo Company

In: – Limits results to a specific section of the profile

• Example: manager in headline
• Only matches “manager” in the profile headline

Range .. – Matches numeric values inclusively between

• Example: GPA 3.8..4.0
• Returns profiles with GPAs from 3.8 to 4.0

With these additional operators combined with core AND/OR/NOT, recruiters gain immense power to develop surgical X-ray searches.

Crafting Effective LinkedIn Boolean Strings

Putting this all together, here is an example of a robust Boolean search string using core and advanced operators:

"technical program manager" AND ("agile" OR scrum) AND san francisco NOT intern in:headline OR summary site:linkedin.com/in/ AND (python OR java)

This surfaces technical program managers with agile/scrum experience in San Francisco (excluding interns) who have Python or Java skills, narrowing specifically to the headline or summary section.

When constructing X-Ray search strings:

• Use AND/OR to require or broaden criteria
• Leverage NOT to filter out irrelevant results
• Apply quotes around exact multi-word matches
• Use wildcards, proximity, and ranges to hone relevancy
• Target specific profile sections with IN:
• Limit by company domain with SITE:

The result is an extremely targeted search matching highly specific candidate conditions.

Step-by-Step Guide to Performing X-Ray Search

Now that we’ve covered syntax, let’s walk through the hands-on process for executing a LinkedIn X-Ray search:

1. Navigate to the main LinkedIn search bar at the top of your homepage.
2. Craft your Boolean search string using AND/OR/NOT operators, quotes, and advanced syntax as needed.
3. For optimal transparency, select “People” as the content type.
4. Choose your desired 2nd degree network visibility.
5. Click the “All filters” link to refine by location, company, profile language, school, etc.
6. Review the first few pages of results for relevance.
7. Tweak your search string if needed to hone results.
8. Export final prospects into a spreadsheet or LinkedIn Recruiter.
9. Review profiles in detail and connect with your top targets!

Following this workflow allows you to build an X-Ray search, analyze the initial results, optimize the query, and then export and engage with your shortlist.

Helpful Tools for LinkedIn X-Ray Search

In addition to LinkedIn’s built-in search, here are some tools that can assist with creating and executing advanced Boolean searches:

• Start broad – Test initial keywords then narrow down the query.
• Iterate frequently – Build search strings progressively vs all at once.
• Analyze results – Review relevance before exporting prospects.
• Use quotes – Wrap specific phrases and titles to improve match accuracy.
