Boolean Search for Recruiters

LinkedIn Boolean Search: A Recruiter's Guide

Your string ran. No error. And the results are still the wrong people. LinkedIn breaks Boolean quietly, so here is what it reads, what it ignores and how to fix it.

The short version

  • Use AND, OR, NOT in capitals, plus quotes and parentheses. That is the whole toolkit on LinkedIn.
  • No wildcards, no proximity search, no + or - symbols.
  • Location goes in the filter, not the string.
  • Most failed searches miss a title variation. The logic is usually fine.

Six rules LinkedIn will not tell you

Type operators in capitals

LinkedIn reads AND, OR and NOT only in uppercase. A lowercase "and" becomes a search word, and you get no warning.

Quote every multi-word title

A space acts as AND. Without quotes, software engineer matches anyone with both words anywhere on the profile.

Group your OR terms

Put title variations inside parentheses. Without them, LinkedIn decides the order for you, and it decides wrong.

Skip wildcards and symbols

LinkedIn does not support *, + or -, or proximity operators. Use AND and NOT, and spell out the variations.

Put location in the filter

Location does not belong in the string. Use the location filter so you keep remote candidates who wrote the city differently.

Keep it short enough to read

Long strings with deep nesting get unpredictable. If you cannot explain your string out loud, LinkedIn cannot follow it either.

Build the string in this order

  1. Start with one title and one skill. Confirm you get results.
  2. Turn the title into an OR group of three to five variations people actually use.
  3. Add the skills that are truly required. Move nice-to-haves to the conversation, not the string.
  4. Add NOT last, and scan what you removed. Every NOT can drop qualified people who mention the word in passing.
  5. Set location and other limits in the filters.

Starter strings you can copy

Illustrative examples written for LinkedIn's keyword field. Swap in the titles and skills your hiring manager actually agreed to.

Software engineer

("software engineer" OR "software developer" OR "SWE" OR "full stack developer") AND (Python OR Java OR JavaScript) NOT "intern" NOT "student"

SaaS sales

("account executive" OR "sales representative" OR "business development representative" OR "BDR") AND (SaaS OR software OR cloud) NOT "intern"

Registered nurse

("registered nurse" OR "RN" OR "BSN") AND ("ICU" OR "emergency" OR "critical care") NOT "student"

Free LinkedIn or Recruiter?

The Boolean is the same in the keyword field on both. What changes is how many results you can see, the filters you can layer on top and whether you can message people outside your network.
