Session: Querying: How to Use 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("manufacturer", "Raven")
    .intersect()
    .whereEquals("color", "Blue")
    .andAlso()
    .whereEquals("size", "Small")
    .intersect()
    .whereEquals("color", "Gray")
    .andAlso()
    .whereEquals("size", "Large")
    .toList();
