Methods, systems, and media are provided for delivering clustered search results for recent and non-recent events by maintaining the identification (ID) numbers of the respective clustered documents beyond the 'fresh' life span of the clustered documents. When clusters are formed according to similar content, an ID number and associated attributes are assigned to each of the clusters. This provides a mechanism to track and retrieve the respective clusters for subsequent delivery of search results. The respective ID numbers of the clusters are maintained, even after the documents are no longer considered 'fresh.' These similar-content clusters are further subdivided according to publication date. This provides individual subdivided clusters for similar content events that occurred at different time spans, which are delivered along with individual non-clustered search results in a SERP.

Clustering web pages on a search engine results page

Techniques are described herein for processing social search results. Such social search results may be included in a relatively higher-ranked (e.g., a highest-ranked) subset of a user's search results and/or selected from a relatively lower-ranked subset of the user's search results in response to a determination that the relatively higher-ranked subset includes social search result(s). In one example, the social search results (or a subset thereof) may be annotated to include publicly available rich metadata. Such metadata may be extracted from user profiles on social networking domains from which the social search results are received. In another example, the social search results (or a subset thereof) may be clustered such that they are consecutively ranked. In yet another example, the social search results (or a subset thereof) may be configured to be displayed in a designated arrangement (e.g., in a grid having multiple columns).

Processing social search results

Techniques are described herein for using intent to access a domain (i.e., domain intent) to provide more search results that correspond to the domain. For example, a rule may specify a maximum number of search results that are allowed to be provided from a domain (or a host that corresponds to the domain) in response to a search query. Each search query may include any number of ngrams. An ngram is a subsequence of elements in a sequence (e.g., a search query). An intent to access a domain may be determined based on one or more of the ngrams in a search query. A number of search results that correspond to a domain may be increased to be greater than the maximum number based on one or more of the ngrams that are included in the search query being associated with the intent to access the domain.
