1. A method for retrieving, organizing and displaying different classifications of sets of search results in response to a text string query, the method comprising: retrieving search history data stored in a data repository in response to determining that the search history data is relevant to identity indicia of a user associated with a text string search query; identifying search resources that are associated with the user identity indicia; identifying a language classification rule of a language indicated by the user identity indicia; classifying the text string search query into constituent primary search terms that are likely to return satisfactory search results in response to a single search as indicated by the retrieved search history data as a function of the identified search resources that are associated with the user identity indicia and the identified language classification rule, wherein the constituent primary search terms are words or phrases; generating a primary set of search results in response to searching network resources for the primary search terms; determining secondary search terms as substitutes for the primary search terms, wherein the secondary search terms are related to the primary search terms and are searched in the retrieved search history in follow-up searches that are immediately subsequent to searches of the primary search terms at a frequency that is less than a specified threshold of frequency, wherein the secondary search terms comprise synonyms and antonyms of the primary search terms; generating a secondary set of search results in response to searching the network resources for the secondary search terms; searching knowledge article resources for articles that comprise background information on the primary search terms or the secondary search terms and retrieving a set of peripheral knowledge article results that each satisfy searches for articles that comprise background information on the primary search terms or the secondary search terms; and displaying the primary set of search results, the secondary set of search results and the set of peripheral knowledge articles to the user in different, respective tabbed sheets that are nested on top of one another in a web-based interface dashboard.
