Question
You initiate a new query to find information about city parks in Australia. You pass the following query to a model:
I need statistics on the number of city parks built in the late 2000s.
The model provides information about city parks across the globe, however. Why?
A. Your query has a broader context and lacks specificity.
B. Your query has sub-queries, giving it a broader perspective.
C. Your model fails to expand your query because of a high specificity.
D. Your model returns multiple queries, running them in parallel.
Answer
A. Your query has a broader context and lacks specificity.
Explanation
The model returned global city park statistics instead of Australian-specific data because your query lacked sufficient specificity to guide the retrieval process effectively (Option A). Here’s why:
How RAG Handles Queries
Retrieval-augmented generation (RAG) combines information retrieval (searching external data) with generative AI (synthesizing responses). For accurate results, the system relies on:
- Precise query phrasing to retrieve relevant documents from a vector database.
- Contextual augmentation to inject retrieved data into the LLM’s response generation.
The Specificity Problem
Your query—“I need statistics on the number of city parks built in the late 2000s”—omits critical geographic context (Australia). This causes:
- Ambiguity in retrieval: Without explicit location markers, the retriever defaults to broader patterns in its vector database, prioritizing terms like “city parks” and “late 2000s” over unstated regional filters.
- Generic generation: The LLM, lacking localized data, synthesizes information from globally indexed sources.
Why Other Options Fail
B (Sub-queries): RAG processes a single query; sub-queries aren’t part of standard workflows.
C (High specificity failure): The issue is low specificity, not excessive constraints.
D (Parallel queries): RAG doesn’t inherently run multiple queries in parallel for a single input.
Fixing the Query
To improve results, refine the query with explicit geographic and temporal filters:
“Provide statistics on city parks built in Australia between 2005 and 2010.”
This directs the retriever to prioritize Australian data sources, ensuring accurate, localized responses.
Key Takeaway: RAG’s effectiveness hinges on query precision. Ambiguous inputs lead to generic outputs, while well-structured queries enable targeted retrieval and generation.
