Abstract: Methods, systems, and computer program products for processing a search query store the search query in one or more persistent storage devices in response to the search query being received. Periodically and automatically thereafter, the search query is retrieved from the one or more persistent storage devices, and source data that relates to the search query is retrieved, using an iterative optimization algorithm, from one or more backend data sources. Responses for the search query are generated based on the source data, and a determination is made of whether each of the responses is notification eligible. A user is notified of each response determined notification eligible.

Abstract: Systems, methods, and computer program products for forming a travel group. A first travel record containing a travel reservation for a first social network user is stored in a database. The travel reservation is published as a trip publication on a social networking system. An inquiry related to the trip publication is received via the social networking system from a client device associated with a second social network user. In response to receiving the inquiry, the one or more processors generate one or more offers for a second trip based on data in the first travel record. A second travel record containing the one or more offers is stored in the database. A link between the first travel record and the second travel record is assigned in a booking folder stored in the database. The one or more offers are communicated to the client device of the second social network user.
