When you create site columns in SharePoint they will have automatically created crawled and managed properties created for them. The naming convention for the properties is explained in detail at TechNet, but it doesn’t mention what properties are set for the associated managed properties.
As far as I know this is the behavior:
- All managed properties are set to retrievable
- All managed properties are set to queryable
- except multi-line and pub image/html/link fields
- Taxonomy fields are also set to searchable (which makes no sense what so ever to me)
Thanks to Graham Sheeley for the idea for this post :)
