model.hybrid^1

• Maximum number of queries is 5
• A document must match at least one clause in queries to be returned in the results

Parameter	Description

The documents’ relevance scores from all query clauses are combined into one score by applying a search pipeline. The maximum number of query clauses is 5. Required.
