**Warning**: Do not manually construct search JSON!

**Correct Usage**: Use the `cplaceJson` field from cplace_search_pages response

**Workflow**:
1. Call cplace_search_pages with your desired filter
2. Take the cplaceJson field from the response
3. Use that value for the search configuration

**Relative Filters** (e.g., "show items referencing current page"):

When using `relativeReference` filters, you MUST provide a real page UID as context:

```
cplace_search_pages(
  searchFilter: [{"relativeReference": {"attribute": "myType.refAttr", "operator": "embeddingCustomEntity"}}],
  embeddingEntityUid: "page/abc123"  // ← Real page UID required!
)
```

Without a concrete `embeddingEntityUid`, the relative filter won't be included in the returned `cplaceJson`.
