+name: docs-search
+description: Agentic search over the DSRs docs via Mixedbread toast-1. Use when answering questions about DSRs concepts, components, or APIs (signatures, predict, modules, IR, holes, optimizers, .dsrs files) instead of grepping docs/ page by page.
+---
+
+# DSRs docs search
+
+The published docs are indexed in a Mixedbread Store (`dsrs-docs`) and
+the Rust sources in `dsrs-code`; both are queried with toast-1 agentic
+search, which decomposes the question into subqueries and returns
+curated chunks. `ask` can also grep the code store for exact symbols.
+
+Run from the repository root (needs `mixedbread` installed and
+`MXBAI_API_KEY` in the environment or `.env`):
+
+```bash
+python3 docs/scripts/search_docs.py search "<question>" [--top-k N] [--json]
+python3 docs/scripts/search_docs.py ask "<question>"
+```
+
+`search` returns raw chunks with source paths — prefer it when you plan to
+read the pages yourself. `ask` has toast-1 compose a grounded answer —
+prefer it for a quick factual check.
+
+- Phrase the query as a full question, not keywords — toast-1 plans its
+  own subqueries from it.
+- Each result prints the source page path (e.g.
+  `docs/components/holes.mdx`) and the chunk text; expect ~10s latency.
+- Read the source page under `docs/` when a chunk looks truncated.
+- If results look stale relative to the working tree, the index only
+  tracks pushed docs — trust the local files and optionally run
+  `python3 docs/scripts/search_docs.py sync` to refresh.
