Abstract
In one embodiment, a method includes receiving, from a user, a search query requesting objects of a first object type. The search query includes an inner query requesting objects of a second object type. The method includes identifying objects of the second object type requested by the inner query using an inverted index of a data store corresponding to the second object type; identifying objects of the first object type requested by the search query using the identified objects of the second object type and a forward index of the data store corresponding to the second object type; and sending search results to the user responsive to the search query, each search result corresponding to an identified object of the first object type.
