}
```

The `solr` field and its `fq`/structured filters are Solr-specific. For a
backend-neutral, forward-compatible product/version filter that works across
**both** OKP transports (the RHOKP MCP server and the legacy Solr path), use the
request field **`okp`** instead. It carries a list of product selections, each
scoping its own exact-match versions (no wildcards), so an invalid
product/version pairing is not representable. Product/version filtering is
query-time only; there is no launch-time product/version configuration.

```json
{
"query": "How do I configure routes?",
"okp": {
"products": [
{ "product": "openshift_container_platform", "versions": ["4.16", "4.17"] }
]
}
}
```

Multiple products are OR'd; a product with no `versions` matches regardless of
version. On the MCP transport each (product, version) pair becomes one search and
the results are merged, deduplicated, and capped at `rag.okp.max_chunks`. Prefer
`okp` over `solr` for product/version filtering; `solr` remains for Solr-specific
needs during the OGX/Solr transition.

Correct the MCP retrieval semantics. OkpMcpRetriever sends one MCP search request with the complete structured products list. It does not run one search for each product/version pair. Update this paragraph to describe the single request and server-side product/version filtering. Keep the documented deduplication and rag.okp.max_chunks cap for the combined response.

In `@docs/user_doc/rag_guide.md` around lines 398 - 422, The RAG guide incorrectly
says the MCP transport issues one search per product/version pair. Update the
paragraph describing OkpMcpRetriever to state that it sends one MCP search
request containing the complete products list, with product/version filtering
performed server-side, while preserving the documented deduplication and
rag.okp.max_chunks cap on the combined response.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

**Prerequisites:**

- The OKP server must be running and accessible at the URL given in `rag.okp.rhokp_url` (or `${env.RH_SERVER_OKP}`).
