UnverifiedA reranker can only reorder within the candidate set already recalled; it cannot pull back a correct answer that never entered the top K.73% similarUnverifiedThe pragmatic approach is to first evaluate retrieval quality independently before connecting the generation stage: if the Top-K retrieved content does not contain the answer, switching to a stronger model cannot remedy the situation.72% similarUnverifiedIncreasing re-ranking intensity or optimizing chunking strategies cannot compensate for the absence of the underlying data structure.70% similarUnverifiedThe answers to multi-hop reasoning queries cannot be derived directly from a single passage but require chained inference across two or more document segments, making standard single-round retrieval largely unsuccessful for such queries.69% similarUnverified在搜索与训练耦合的循环中，仅保存最新权重无法完整恢复实验状态，因为模型检查点与搜索档案共同描述同一个演化中的实验，恢复时必须成对还原。68% similar
