Abstract
Systems and methods are provided for efficient calculation of sets of distinct results in an information retrieval service. A query is received having at least one requested attribute and one or more conditions. For each row identifier in a database table that matches the one or more conditions, a tuple of value identifiers having an entry for each requested attribute is calculated. A unique number is generated and assigned to the tuple for each distinct combination of the value identifiers. Duplicate entries in the tuple listing are identified and removed, so that a result set provides only distinct results.
