Production-VerifiedRunning a Boolean search that returns hundreds of irrelevant candidate profiles is just as problematic as getting zero results. When a search yields high volumes of false positives, recruiters are forced to spend valuable time manually reviewing unqualified resumes. This issue usually indicates an under-constrained search query, missing quotation marks, or polysemous keywords (words that carry multiple meanings across different industries).
Step-by-Step Execution Guide:
1
To tighten an overly broad Boolean search string and restore candidate relevance, apply these four optimization steps:
1
Enclose Compound Phrases in Quotation Marks: The most common cause of irrelevant results is forgetting to use quotation marks around multi-word job titles or terms. If you search for Project Manager Scrum Master without quotation marks, the search engine treats it as Project AND Manager AND Scrum AND Master.
2
Target the Title Field Rather Than Full Profiles: When searching on platforms like LinkedIn Recruiter or internal ATS databases, move your role-specific Boolean string into the Job Title field or use title operators (intitle: on Google).
3
Introduce Core Technical Modifiers: If your search for “Business Analyst” returns hundreds of entry-level resumes, add a mandatory technical skill using AND: (“Business Analyst”) AND (“SQL” OR “Tableau” OR “Power BI”).
4
Apply Controlled Negative Exclusions: If your results consistently surface a specific irrelevant profile type, add a focused NOT operator at the end: NOT (“Consultancy” OR “Staffing Agency” OR “RPO”).

Recruiter Pro Tip from the Field
Review the first twenty candidate profiles returned by your search query. Identify the most common irrelevant job title or keyword across those profiles, and add it directly into an exclusion block using the NOT operator.
