Abstract
A non-transitory computer readable storage medium includes executable instructions to receive primary matched values with corresponding document identifications. The primary matched values correspond to a specified primary value, for example expressed in a search query. A secondary scalar index is scanned to match the document identifications with secondary matched values with corresponding secondary values. A tertiary scalar index is scanned to match the document identifications with tertiary matched values with corresponding tertiary values. The secondary values and tertiary values are provided as tuples. Each tuple has the specified primary value, a secondary value, a tertiary value and frequency indicia.
