What is the effect of adding "type": "best_fields" in a multi-match query?
AFilters documents to only those matching all fields
BReturns documents matching the best single field score
CReturns documents matching all fields equally
DSorts documents by field length
Step-by-Step Solution
Solution:
  1. Step 1: Understand multi-match "best_fields" type

    This type scores documents based on the best matching field, not requiring all fields to match.

    Returns documents matching the best single field score matches this behavior. Returns documents matching all fields equally implies equal scoring, Filters documents to only those matching all fields requires all fields, and Sorts documents by field length is unrelated.
  3. Final Answer:

    Returns documents matching the best single field score -> Option B
  4. Quick Check:

    "best_fields" = best single field score [OK]
Quick Trick: "best_fields" picks highest scoring field match [OK]
