How can you modify a MultiQueryRetriever to prioritize certain queries over others?
AUse only the first query and ignore others.
BRepeat important queries multiple times in the list.
CAssign weights to queries and adjust retriever scoring accordingly.
DSort queries alphabetically before passing them.

    Assigning weights allows the retriever to score and prioritize results from important queries.

  2. Step 2: Evaluate other options

    Repeating queries is inefficient, sorting alphabetically does not affect priority, ignoring queries loses recall.

  3. Final Answer:

    Assign weights to queries and adjust retriever scoring accordingly. -> Option C

  4. Quick Check:

    Use weights to prioritize queries = D [OK]
Quick Trick: Use weights to prioritize queries in retrieval [OK]
Common Mistakes:
  • Repeating queries instead of weighting
  • Sorting queries expecting priority change
  • Ignoring queries to prioritize
