1. A computer-implemented method of generating domain specific search results, the method comprising: displaying a page of a web site obtained from a first search, the page having a domain tuned search interface that is embedded in the page and returns search results based on a domain tuned search definition that identifies subject matter content of the web site; receiving a search input at the embedded domain tuned search interface, the search input being separate from the domain tuned search definition; using a search engine, that is associated with the embedded domain tuned search interface, to search a network of sites and return generic, non-domain specific search results based on the search input; generating, from the non-domain specific search results, domain specific search results by ranking the non-domain specific search results, using a computer processor, based on how similar in terms of subject matter content the non-domain specific search results are to the domain tuned search definition, wherein ranking the non-domain specific search results comprises: accessing a definition data store that stores a plurality of search definitions, each of the search definitions identifying a topical area of interest; and selecting the search definition from the plurality of search definitions stored in the definition data store, based on an identification of the embedded domain tuned search interface through which the search input is received; and outputting the domain specific search results.
