Semantic Search outperforms Deep Agentic Search in code QA, study finds

A new study published on arXiv investigates two primary methods for code question answering within large repositories: Semantic Search and Deep Agentic Search. Researchers found that Semantic Search outperformed Deep Agentic Search, correctly answering 65.2% of questions compared to 46.2%, and did so at less than half the cost. The study identified that Deep Agentic Search, despite being a preferred design for protecting agents from context pollution, introduced a significant failure mode where sub-agents provided incorrect answers confidently. AI

IMPACT This research suggests that current practices in code agent design may be suboptimal, potentially impacting the efficiency and accuracy of AI-assisted software development.

    Deep Agentic Search for Repository-Level Code Question Answering: An Empirical Study

    Code agents spend much of their effort simply locating the right code inside a repository. Two approaches dominate current practice. In Semantic Search, the agent retrieves code blocks from a vector index built from the repository in advance. In Deep Agentic Search (also known as…
