UnverifiedWhen splitting text by token count, a chunk size of 200–500 tokens is typically set.68% similarUnverifiedIn traditional RAG document chunking, documents are split into fixed-length segments (e.g., 256 characters) with some overlap between segments to maintain semantic coherence67% similarUnverifiedIn RAG document preprocessing, text chunks are typically split into 200–1,000 tokens; chunks that are too large introduce noise, while chunks that are too small lose context.64% similarUnverified文档切分中块太大则检索精度下降，块太小则丢失上下文语义，设置50-100 token的重叠能避免关键信息被切断63% similar
