Testing with SXA 1.2 on Sitecore 8.2 u1/u2.

I'm trying to query a list of pages marked as featured.

Here is what I have setup:

 - *Custom Page* template inherits from *Page*.
 - Checkbox field is added with **IsFeatured** field.

 - Query defined to return featured pages.

<!-- language: lang-plaintext -->

    +location:{29E0ED6F-452B-45A0-B799-C51EBD14970A};template:{13de59b4-ad71-4542-9ce0-a0483422e768};custom:isfeatured|true

  - The query item does not have a way to build the query, so I used the datasource

Unfortunately, when I test the page no results are returned.

### Update

Test with a new query that has a `+` for each setting but does not change the behavior.

## Update 2
Oddly, when I move the query to the Data Source field and clear the Source Type I get an error. Not seen this before.
