Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with six documented parameters, so the schema carries the semantics. The description only echoes 'matching requested text' and 'specified document', adding no syntax, matching-rule, or interaction detail (e.g. how 'all' vs 'search' interact) beyond what the schema already states. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
