[zilliztech/zilliz-plugin developer guide]: dimension mismatch means the vector size does not match the collection, check len(vector) against the collection dimension. node not match means cluster scaling is in progress, wait a few seconds and retry with backoff. collection not found means a wrong name or it was never created, check list_collections. rate limit exceeded means too many requests, implement backoff and check quotas. For cold-start search latency, call load_collection first; insert bottlenecks go away with batch_size 5000.

Context: Zilliz Cloud operations fail with cryptic errors. The official Zilliz developer guide documents the common error diagnostics table.
