class StreamingGET with body payload — no resources created. Returns the threads in a tracing project matching the query passed as the request payload. Results are filtered by the given time range and optional filters, with cursor-based pagination.
When ai_search is set, Accept: text/event-stream is required; requests
without it return 406. AI search is unavailable on deployments that route
queries to the v1 backend and returns 501 there.
Self-hosted deployments require LangSmith v0.16 or later.
Yields the items of query one at a time across pages, following the next page cursor.
