1. A computer-implemented method to store related sparse data within a search index, the method comprising: detecting sparse data within content to be indexed, the sparse data comprising a data point related to an entity by determining if the content matches one or more classification rules; determining a number of matches and a confidence of the matches for the one or more classification rules; in response to a determination that there is at least one match, creating an integer array for the data point such that a value associated with the data point is one or more of a count value and a confidence value based on the determined number and confidence of the matches; in response to receiving a request from a user to perform a query on the search index that includes the data point, transforming the query to a corresponding range based on an identifier of the entity; and upon execution of the query, providing query results to the user.
