16. A computer-implemented method for searching for multidimensional social media content, comprising: receiving, from a user, a request for a search of social media content, wherein said search is directed to a search term selected by said user, wherein said search term comprises one or more of a social contributor, social entity and social tag; conducting, with the aid of a computer processor operatively coupled to a database of social media content, a search of social media content in said database, wherein said search of social media content is directed to said search term, wherein said social media content in said database is collected from a plurality of social media providers, wherein said social media content is organized in said database based upon relationships between social entities, social contributors and social tags identified in said social media content, wherein said social contributors have posted said social media content on said plurality of social media providers, wherein each of said social entities is a subject of an individual social media content, wherein said social entities are not social contributors for said collected social media content, and wherein said relationships are based upon social tags present in social media content of social entities and social contributors; sorting one or more results of said search by a social score that is calculated from a social engagement score and a social post score, wherein said social engagement score is based on a social relevance of said social contributors and social entities and is determined by the number of friends, fans, followers, or other measurement that assesses a social network presence of said social contributors and social entities, wherein said social post score is based on a degree of interaction of a social contributor or a social entity among said social contributors and social entities with social posts at one or more remote social media providers, wherein said degree of interaction is determined as a net of positive and any negative interactions by said social contributor or social entity with respect to said social posts on said one or more remote social media providers; grouping, with the aid of a computer processor, at least a portion of said one or more results of said search by social contributor, social entity and social tag to provide a first subset and a second subset of results, wherein the second subset has a hierarchical relationship to the first subset; generating a social stream from at least a portion of said one or more results of said search, wherein said social stream includes social media activities of a social entity or social contributor that can be searched, grouped and filtered by said user; and displaying, on a graphical user interface of said user including a first panel and a second panel, said social stream comprising the first subset and the second subset in said first panel in sequence upon said search; said hierarchical relationship between said first subset and said subset in said second panel; and a social search path that is indicative of a search or navigation path taken by said user in arriving at said social stream comprising said first subset and said second subset, thereby presenting said results to said user hierarchically across multiple dimensions to reflect their relationship to said search term.
20. The computer-implemented method of claim 16 , wherein said relationships are stored in memory as indexes to permit a search of said social media content based upon said relationships by said user.
