Existing benchmarks also suffer from data contamination, label noise, and degenerate binary relevance. In this paper, we introduce \\textsc{CoREB}, a contamination-limited, multitask \\underline{co}de \\underline{r}etrieval and r\\underline{e}ranking \\underline{b}enchmark, together with a fine-tuned code reranker, that goes beyond retrieval to cover the full code search pipeline. \\textsc{CoREB} is built from counterfactually rewritten LiveCodeBench problems in five programming languages and delivered as timed releases with graded relevance judgments. We benchmark eleven embedding models and five rerankers across three tasks: text-to-code, code-to-text, and code-to-code. Our experiments reveal that: \\circone code-specialised embeddings dominate code-to-code retrieval (${\\sim}2{\\times}$ over general encoders), yet no single model wins all three tasks; \\circtwo short keyword queries, the format closest to real developer search, collapse every model to near-zero nDCG@10; \\circthree off-the-shelf rerankers are task-asymmetric, with a 12-point swing on code-to-code and no baseline net-positive across all tasks; \\circfour our fine-tuned \\textsc{CoREB-Reranker} is the first to achieve consistent gains across all three tasks. The data and model are released.","meta_description":"🤗 Upvotes: 22 | cs.SE, cs.AI Authors: Siqiao Xue, Zihan Liao, Jin Qin, Ziyin Zhang, Yixiang Mu, Fan Zhou, Hang Yu Title: Beyond Retrieval: A Multitask Ben…","key_points":[],"chapters":[],"topics":[],"duration_seconds":1274,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/daily-paper-cast-7079649/episodes/beyond-retrieval-a-multitask-benchmark-and-model-for-code-search/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/daily-paper-cast-7079649/beyond-retrieval-a-multitask-benchmark-and-model-for-code-search.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
