**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 this attribute

**Note**: Only active when `cf.cplace.visualization.dataSource` = `search`. The search results become available to the cplaceJS script as the `pages` variable.
