Abstract
A data processing method comprising the computer-implemented steps of using a database index key processing module in a computer, generating row keys for a data store, the data store comprising data records, each comprising at least a first element and a second element, each of the row keys comprising at least: a first portion comprising a first encoded value for the first element of a corresponding data item of the data records, a second portion comprising a second encoded value for the second element of the corresponding data item of the data records, storing the data records using the row keys, using a query processing module of the computer, receiving a search query comprising a first filter for the first element, translating the first filter into at least the first portion of a search key, and searching the dataset using the search key.
