Abstract: A flexible listings search system can receive and return results for flexible listing searches. For example, the system can perform micro-flexible searches (e.g., plus or minus a few days) or super flexible searches (e.g., a time span in one or more months), using listing arrays that can be rapidly accessed to efficiently identify and return results. The search system can further perform flexible destination searches for different categories of accommodations for display in a viewport (e.g., map bounding box). The system can further perform fuzzy searches to identify and return broader results for flexible queries.

Abstract: A search system that receives and returns results for split stays is described. The search system receives, from a searching end-user, a listing request specifying a multiple-day length of stay parameter. The search system determines that the multiple-day length of stay parameter of the listing request transgresses a minimum length of stay threshold and, in response, generates a combined listing that includes a first listing of the plurality of listings associated with a first portion of the multiple-day length of stay parameter and a second listing of the plurality of listings associated with a second portion of the multiple-day length of stay parameter. The combined listing is presented with one or more other listings of the plurality of listings that match the listing request in a ranked order.

Abstract: Systems and methods for providing updates to a data store are described. A data store may receive, process and distribute update information in a substantially orderless manner. This may include implementing an “eventually consistent” design pattern, in which all operations include an object identifier associated with one of the objects in the data store, an information attribute identifier, an initial state, and a final state. Examples may include comparing the initial state included in the update instruction to a current state of one of the objects. If the initial state and the current state are the same, the current state of the object may be modified to match the final state of the update instruction. If the initial state and the current state are not the same, the update instruction may be sent to a redrive queue, from which the update may be reprocessed at a later time.

Abstract: Disclosed are various embodiments for custom result set definitions. A result set definition is obtained responsive to a request from a client. A result customization application generates and executes application program interface calls to generate response data having a fixed schema. The result customization application performs transformations on the response data to generate a result set conforming to the result set definition.

Abstract: A merchant system is disclosed that can provide multiple online marketplaces that utilize marketplace product catalog layering. Product catalogs associated with each marketplace may be defined and layered such that products sold by one marketplace may be displayed on and purchased by way of another marketplace. The merchant system might also provide a unified electronic shopping cart for storing purchases made at multiple marketplaces, a unified checkout user interface for completing the purchase of items from multiple marketplaces, and a unified order management user interface for managing purchases made from multiple marketplaces.
