Abstract: Methods and Systems to browse data items are described. The system receives selections, over the network at a computer based system, from a client machine and uses the selections to identify a level of interest of a first user for a first browsing set. The first browsing set includes a first browsing concept. The system receives a query from, over the network at a computer based system including a keyword. The system automatically selects the first browsing set based on the query and the elevated level of interest of the first user for the first browsing set. The system generates a first user interface including the browsing concept. Finally, the system communicates the first user interface including the browsing concept to the client machine.

Abstract: A method and system to process a selection of a browser back button at a client machine. The system receives a browser back button selection, associates the browser back button selection to a first user interface identifier, retrieves the first user interface based on the first user interface identifier, associates the first user interface identifier to a second user interface, and displays the second user interface responsive to selection of the browser back button.

Abstract: Methods and systems to process a selection of a browser back button are described. The system includes a server that receives a request, over a network, for an initial user interface and communicates the initial user interface to a client machine. The initial user interface includes a client application program that monitors and identifies whether a storage location in a hidden frame is updated by a browser. The browser updates the storage location with a first user interface identifier in response to receipt of a single browser back navigation element selection. The client application program associates the first user interface identifier to a second user interface identifier responsive to the identification of the storage location as being updated. The client application program displays the second user interface in a visible frame responsive to the identification of the storage location as being updated.

Abstract: Methods and Systems to browse data items. There is provided a method and system to enable a buyer to browse listings that are listed, by sellers on a network-based marketplace and stored in a data resource. There is further provided a method to cancel characteristics used to identify listings that are listed by sellers on a network-based marketplace.

Abstract: Example systems and methods of processing a data search request are presented. In one example, a data search request including a plurality of constraints is received. Each of the plurality of constraints is of one of a plurality of constraint types. At least one of the plurality of constraints of a first constraint type is expanded to one or more constraints of at least one other constraint type. A plurality of search definitions is formulated utilizing the plurality of constraints. Each of the plurality of search definitions includes a unique constraint set excluding at least one of the plurality of constraints. A plurality of searches is performed using the plurality of search definitions to generate a plurality of search results. Data item counts corresponding to the search definitions are calculated. The data item counts and the corresponding search definitions are communicated to a client machine.

Abstract: A method and system to process a data search request. The system includes a query controller module to receive the data search request that includes constraints; a reduced constraint builder module to formulate a plurality of search definitions that are formulated to exclude at least one constraint; and a search engine to perform searches of a data source to generate search results and to utilize the search results to calculate counts of data items that respectively correspond to the search definitions. The query controller module communicates the counts of data items and the corresponding search definitions to a client machine. Each of the search definitions is formulated to include a constraint set.
