Abstract
Multi-type attribute indexes may be implemented for document databases. When a request to perform a query at a document database is received that is directed toward in indexed attribute that has multiple data types for values stored in the multi-type attribute index, a predicate in the query may be replaced with a different predicate that is applicable to search the multi-type attribute index according to a sort order for the multiple data types stored in the at multi-type attribute index. A plan that includes the different predicate may be performed in order to provide a result of the query to a user.
