Hi
I have been surfacing news articles based on a custom content type to a home page  using the new Content Search.  My content type has a mixture of standard site columns and managed terms. Now like the old CQWP, I want to filter on items that have Yes/No Site column value.
- My Site Column is automatically added Managed Property with non editable attributes (Editable, Queryable etc) and can be viewed my SC: Search Schema
- I can display it as one of the Property Mappings in the Web Tool Part panel
- It shows  a “Yes” or “No” value under my rollup image
- I then refine my query and can select the a property (site column) as I build up my query as in only return items when IsTheBestDayofWeekFridayOWSBOOL manual value equals “Yes”
 path:”http://MyPORTAL”  ContentTypeId:0x010100C568DB52D9D0A14D9B2FDCC96666E9F2007048130EC3DB064584E21995537AF39*  IsTheBestDayofWeekFridayOWSBOOL=”Yes”
attempt to filter on my managed property does not show any of my articles  – I am assuming my syntax is wrong rather than the SIte column not in the index since it appears to be crawled.
How hard can this be!!!!!!
You should try removing that part of the query filter and changing the Display Template to “Diagnostic” this will return for those items all the MP you can work with and their values. This way you can easily adapt to match the values. Or use the Search Tool on Codeplex whatever is easier.
