The specification lists the following two capabilities, which seem to overlap. If not, their meaning is unclear.

> Ability to provide query (enumCapabilityQuery):
> 1. none (no query support)
> 2. metadataonly (only metadata)
> 3. fulltextonly (only full text query)
> 4. both (both fulltext and metadata capabilities provided)

> Full-text search support level in query: This is an enumeration with the following allowable values:
> 1. No full-text support (i.e, a text-search-predicate is not allowed in the WHERE clause of a query)
> 2. Full-text only (i.e, only text-search-predicate is allowed in the WHERE clause of a query)
> 3. Full-text + structured/typed search on Properties (i.e, all search predicates are supported in the WHERE clause of a query)
