Hybrid search (semantic + keyword) in Prompt Engineering / GenAI - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is hybrid search in the context of information retrieval?

Hybrid search combines semantic search and keyword search to improve finding relevant information by understanding meaning and matching exact words.

How does semantic search differ from keyword search?

Semantic search understands the meaning behind words and finds related concepts, while keyword search looks for exact word matches.

Why combine semantic and keyword search in hybrid search?

Combining both helps find results that match exact terms and also those that are conceptually related, improving accuracy and recall.

What role do embeddings play in semantic search?

Embeddings convert words or sentences into numbers that capture their meaning, allowing semantic search to compare concepts effectively.

Name one challenge when implementing hybrid search.

Balancing the weight between semantic similarity and keyword matching to get the best search results can be challenging.

What does hybrid search combine?

A Only keyword search

B Image search and video search

C Semantic search and keyword search

D Only semantic search

Hybrid search uses both semantic and keyword search to improve results.

Which search type understands the meaning behind words?

A Keyword search

B Semantic search

C Boolean search

D Exact match search

Semantic search captures the meaning and context of words.

What is a key benefit of hybrid search?

A Better balance of exact and related results

B Faster indexing

C Only finds exact word matches

D Removes all irrelevant results

Hybrid search balances exact keyword matches with semantic understanding.

What technology helps semantic search compare meanings?

A Inverted index

B Regular expressions

C Stop words

D Embeddings

Embeddings turn text into numbers that represent meaning.

What is a challenge in hybrid search?

A Balancing semantic and keyword scores

B Not indexing data

C Using only semantic search

D Ignoring keyword matches

Finding the right balance between semantic similarity and keyword matching is difficult.

Explain how hybrid search improves search results compared to using only keyword or semantic search.

Think about how understanding meaning and exact words together helps find better answers.

Describe the role of embeddings in semantic search within a hybrid search system.

Consider how computers understand text meaning using numbers.
