Disclosed is a mechanism for searching formatted data on sequential storage devices, such as rotating disks or tape and selecting records based on user-defined search expressions. A Structured Query Language, SQL, is an example of a source of search expressions. Since the data are read serially from the device, it may not be possible to parse the parameters of the search expression to match the serial sequence of the data or, parameters may be repeated in different sub-expressions or compared with data read from the device rather than predefined con- stants.
