Using Intersect
To return only documents that match all provided sub-queries, use the intersect method which enables RavenDB to perform server-side intersection queries.
Syntax
IDocumentQuery<T> intersect();Example
// return all T-shirts that are manufactured by 'Raven'
// and contain both 'Small Blue' and 'Large Gray' types
List<TShirt> tShirts = session
.query(TShirt.class, TShirts_ByManufacturerColorSizeAndReleaseYear.class)

.whereEquals("color", "Blue")
.andAlso()
.whereEquals("size", "Small")
.intersect()
.whereEquals("color", "Gray")
.andAlso()
.whereEquals("size", "Large")
