Boolean search is a query technique that combines keywords with logical operators such as AND, OR, and NOT, alongside grouping with parentheses and exact-phrase quotation marks. Recruiters use it to filter large candidate databases, LinkedIn, Google, and ATS records into a tightly scoped shortlist.
A typical Dutch sourcing string might combine a job title, a skill set, a location, and a language requirement. For example, pairing variations such as "software engineer" with skills like Python or Java, excluding irrelevant industries, and restricting to the Randstad region. Good Boolean strings balance precision and recall: too narrow and strong candidates are missed, too broad and the list becomes unusable.
Boolean search is most effective when combined with synonyms, Dutch and English title variants, and location qualifiers relevant to the local market. Recruiters should document reusable strings per role family to maintain consistency across searches and to support auditable, compliant sourcing practice.
