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
def intersect(self) -> DocumentQuery[_T]: ...Example
# return all T-shirts that are manufactured by 'Raven'
# and contain both 'Small Blue' and 'Large Gray' types
tshirts = list(
session.query_index("TShirts/ByManufacturerColorSizeAndReleaseYear")
.where_equals("manufacturer", "Raven")
.intersect()
.where_equals("color", "Blue")
.and_also()
.where_equals("size", "Small")
.intersect()
.where_equals("color", "Gray")
.and_also()
.where_equals("size", "Large")
.of_type(TShirt)
