A:Freshness control keeps index content aligned with updated source documents. This does not directly meet the case requirement to place the best evidence near the top.
B:Metadata filtering restricts retrieval by fields such as document date, language or category. This does not directly meet the case requirement to place the best evidence near the top.
D:Chunking divides large documents into passages suitable for focused retrieval. This does not directly meet the case requirement to place the best evidence near the top.
Question 655
A contract assistant cites a policy deleted last week. Which operational control matters?
- Metadata filtering
- Semantic embeddings
- Relevance ranking
- Source freshness control
Explanation
Correct Answer
D:Source refresh should remove stale content. Freshness control keeps index content aligned with updated source documents.
Incorrect Answers
A:Metadata filtering restricts retrieval by fields such as document date, language or category. This does not directly meet the case requirement to keep the index synchronized with source changes.
B:Embeddings represent query and passage meaning as vectors for similarity matching. This does not directly meet the case requirement to keep the index synchronized with source changes.
C:Relevance ranking orders retrieved matches by estimated usefulness to the query. This does not directly meet the case requirement to keep the index synchronized with source changes.
Question 656
A team wants to know whether the correct paragraph appears in the top five hits for test questions. What activity is this?
- Semantic embeddings
- Relevance ranking
- Metadata filtering
- Retrieval benchmark evaluation
Explanation
Correct Answer
D:Retrieval benchmarks measure evidence coverage. Benchmark evaluation checks whether the system finds the correct passages on known questions.
Incorrect Answers
A:Embeddings represent query and passage meaning as vectors for similarity matching. This does not directly meet the case requirement to quantify passage retrieval relevance.
B:Relevance ranking orders retrieved matches by estimated usefulness to the query. This does not directly meet the case requirement to quantify passage retrieval relevance.
C:Metadata filtering restricts retrieval by fields such as document date, language or category. This does not directly meet the case requirement to quantify passage retrieval relevance.
Question 657
An assistant indexes large manuals with no parsing and cannot retrieve narrow answers. What should be changed?
- Document chunking
- Semantic embeddings
- Source freshness control
- Metadata filtering
Explanation
Correct Answer
A:Document chunking enables focused search. Chunking divides large documents into passages suitable for focused retrieval.
Incorrect Answers
B:Embeddings represent query and passage meaning as vectors for similarity matching. This does not directly meet the case requirement to turn long manuals into retrievable segments.
C:Freshness control keeps index content aligned with updated source documents. This does not directly meet the case requirement to turn long manuals into retrievable segments.
D:Metadata filtering restricts retrieval by fields such as document date, language or category. This does not directly meet the case requirement to turn long manuals into retrievable segments.
Question 658
A search pipeline relies only on exact words and misses synonymous requests. What feature could improve recall?
- Source freshness control
- Semantic embeddings
- Retrieval benchmark evaluation
- Metadata filtering
Explanation
Correct Answer
B:Semantic vectors can match conceptually similar terms. Embeddings represent query and passage meaning as vectors for similarity matching.
