Abstract: Federated search is disclosed. A result associated with a search of a content source not natively configured to provide content type data for content items is received. A content type is associated with a content item included in the result based at least in part on information associated with the result.

Abstract: A system for moving search results visibly comprises an interface, a processor and a memory. The processor is configured to a) determine an ordering of one or more results in a subsequent set of search results as merged into a displayed set of search results; b) determine one or more interleaving positions for the subsequent set of search results in the displayed set of search results; c) cause the creation of one or more blank spaces in the one or more interleaving positions; and d) cause a display of one or more results in the subsequent set of search results in the one or more blank spaces.

Abstract: Dynamic update of a displayed set of search results is disclosed. One or more search results in a displayed set of search results are shown to move within the display to create a space. One or more additional search results are displayed in the space. In some embodiments, animation techniques are used to provide a more nearly continuous and easy to comprehend update of the displayed results.

Abstract: Determining a relevancy ranking score is disclosed. A query is received that includes one or more constraints. One of the one or more constraints includes an operator. A search result based on the query is received. The relevancy ranking score for the received search result is determined based at least in part on the operator associated with the one or more constraints of the query.

Abstract: Determining a relevancy ranking score is disclosed. An indication is received that a relevancy ranking score algorithm is to be tuned to a selected preference. The relevancy ranking score algorithm is updated based at least in part on the selected preference, wherein the relevancy ranking score of a search result resulting from a search query is based at least in part on one or more constraints of the search query.

Abstract: Migration of content when accessed using federated search is disclosed. A content item is received as a result of a search of a content source not natively configured to provide content type data for content items. The content item is stored as a part of a repository that is organized by content item type, including by associating with the content item a content type.

Abstract: Presenting search results is disclosed. At least a portion of a first set of results is displayed in an order determined at least in part by a corresponding attribute of each respective result. An updated display of at least a portion of a combined set that includes at least a part of the first set of results and at least a part of the second set of results in an order determined at least in part by the corresponding attribute of each respective result in the combined set is displayed automatically.

Abstract: A federated search engine groups search results from information sources using attributes of the search results. In grouping the search results, a first set and a second set of attributes are extracted from content in each set of search results received using information source wrappers. The first set of attributes defines a main clustering strategy, and the second set of attributes defines a sub-clustering strategy. A main grouping of the sets of search results received from the information sources is generated using the first set of attributes. The main grouping of search results includes a plurality of labeled groups with a plurality of search results in each group. A sub-grouping of search results is generated for each labeled group of search results in the main grouping of search results using the second set of attributes.

Abstract: A method of automatically generating a wrapper for extracting variable data from a Web-site includes providing a result page from the Web-site; detecting repeating sequences of HTML tags in the page, wherein a sequence includes at least two HTML tags enclosing at least one text field for containing variable data; determining the longest and most frequently repeated sequence; generating an expression for extracting variable data using the first determined sequence; and assigning a label to the at least one text field within the first determined sequence. The method is automatic in that no annotated, sample pages are required for the method to work. Labels can be generated by a hypothesizing algorithm or by evaluating the HTML tags for possible information or by some other technique.
