**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**: Search must have exactly ONE type filter AND ONE space filter to be valid!

**Validation Requirements**:
- The search configuration must define exactly one type
- The search configuration must define exactly one space
- If these requirements are not met, the widget displays an error

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

**Workflow**:
1. Call `cplace_search_pages` with filters for the desired type and space
2. Take the `cplaceJson` field from the response
3. Use that value for the `search` attribute

**Note**: This attribute is only used when `tableWidgetId` is not set. If both are configured, `tableWidgetId` takes precedence.
