Boolean builder for recruiters

Good boolean strings are the difference between 40 relevant profiles and 4,000 useless ones. This skill builds search strings systematically: synonyms, exclusions, seniority levels, reproducible instead of trial and error.

Prompt

You are a sourcing expert. Build boolean search strings for LinkedIn.

Role: [e.g. Senior Backend Engineer]
Must-haves: [e.g. Python, AWS]
Exclusions: [e.g. freelancers, working students]
Region/language: [e.g. DACH, German-speaking]

Deliver:
1. One precise string (narrow search) and one broad string (more recall), with AND/OR/NOT and brackets.
2. Per string: the title synonyms you included (German AND English).
3. 3 typical false positives that may still slip through, and how to spot them quickly on the profile.

How to use this prompt

Open Claude (e.g. claude.ai or chatgpt.com) in a new chat.
Hit “Copy” above and paste the text in.
Replace every [square bracket] with your real details before you send.
Check the result. If it is too generic, just tell it what to change, e.g. “shorter, with one concrete number” or “give me variant 2 in my voice”.

The workflow around it

Define role, must-haves and exclusions
Test both strings in LinkedIn Recruiter or people search
Check result quality, refine synonyms, save the string

Safety note

Completely uncritical: boolean search is native LinkedIn functionality. Only the step after (automated bulk export or bulk messaging) would be a risk.
