An unbounded redundant discrete fact data store for providing answers to specific fact-based search queries is provided. Facts are stored discretely by the data store with information stored with each discrete fact for locating the discrete fact in response to a search query or browse request. The core of the data store includes subject-indicator-fact sets. Each discrete fact represents a particular facet of a particular subject. Accordingly, the data store includes a subject and zero or more indicators for each discrete fact, facilitating look-up of the discrete facts. Additionally, each subject may have zero or more subject classifications and zero or more parent/child relationships with other subjects, further facilitating filtering and look-up of discrete facts.
