1. A system, comprising: a memory comprising program instructions; and one or more processors coupled to said memory, wherein the program instructions are executable by at least one of said one or more processors to implement a search result conditioning component configured to: determine a search result group comprising a plurality of search results, wherein the plurality of search results are results of a search query, wherein the search result group includes a connected graph comprising multiple nodes and multiple edges each connecting a distinct pair of nodes, wherein each node represents a search result of said plurality of search results, wherein each node includes a search result identifier that is different than the other nodes of the multiple nodes, wherein each edge indicates the pair of nodes connected by that edge are similar search results with a measure of similarity between the pair of nodes greater than a requisite measure of similarity; for each node representing a given search result of the search result group: apply one or more similarity criteria to each of the multiple nodes of the connected graph to identify a respective similar group of nodes that are similar to the given search result; sort the nodes of the similar group of nodes and the node representing the given search result into an order based on the respective search result identifiers of the nodes of the similar group of nodes and the node representing the given search result such that each sorted group includes a respective first node occurring before the one or more other nodes within the order of the sorted group; and responsive to the order of nodes resulting from the sort, label the given search result with the search result identifier of the respective first node from the sorted similar group of nodes; wherein at least some search results of the search result group are assigned the same label; modify the search result group, wherein to modify the search result group the search result conditioning component is configured to remove at least one search result from the search result group dependent upon the label assigned to the at least one search result being shared with at least one other search result of the search result group; and output the modified search result group.
