**Best Practice**: Only use this attribute when no table widget on the page holds the data to visualize. Prefer connecting to a table via `tableWidgetId` for synchronized filtering and dynamic updates.

**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 criteria
2. Take the `cplaceJson` field from the response
3. Use that value for the `search` attribute

**Note**: Only used when `tableWidgetId` is not specified. The search must target a single type for the widget to be valid.
