Abstract: In one embodiment, a method includes accessing a first set of objects, identifying one or more configuration files based on attributes of the first set of objects and attribute types specified by the configuration files, receiving from a user an input of a query constraint corresponding to one of the identified configuration files, identifying a second set of objects matching the first query constraint, and sending to the user search results corresponding to the second set of objects.

Abstract: Systems, methods, and non-transitory computer-readable media can obtain a set of configuration options for an event, the configuration options specifying information for grouping users that are participating in the event. A determination is made that a set of users have confirmed their participation in the event. Each user in the set is assigned to a respective group based at least in part on one or more criteria specified in the configuration options for the event. Each user assigned to a group is provided with information describing at least their respective group.
