Elasticsearch - Search Results and Scoring

What does the from parameter control in an Elasticsearch query?

AThe total number of results to return
BThe starting index of the search results to return
CThe sorting order of the results
DThe fields to include in the results
Step-by-Step Solution
Solution:
  1. Step 1: Understand the role of from

    The from parameter sets the offset, meaning it tells Elasticsearch where to start returning results from.
  2. Step 2: Differentiate from size

    The size parameter controls how many results to return, not the starting point.
  3. Final Answer:

    The starting index of the search results to return -> Option B
  4. Quick Check:

    from = start index [OK]
Quick Trick: Remember: from = start index, size = count [OK]
Common Mistakes:
MISTAKES
  • Confusing from with size
  • Thinking from controls sorting
