In plain words: SOSL (Salesforce Object Search Language) is a search language designed to scan text across multiple unrelated standard and custom objects in a single query, returning separate lists of matching records efficiently. While SOQL queries individual database tables with exact field matching, SOSL indexes text fields across your entire org. Pairing SOSL with a custom Visualforce or Lightning interface allows developers to create unified global search panels tailored to custom business workflows.
