<p>Method and computer system for retrieving data from a data storage system. The data storage system receives a query comprising a Boolean expression that includes a first portion and at least a second portion. The data storage system determines a first result set (361) comprising result flags (C-FLAG1) in compliance with the first portion and at least a second result set (362) comprising further result flags (C-FLAG2) in compliance with the second portion. Each result flag is related to a corresponding result identification number (351, 352) and is related to a corresponding InfoCourse anchor (310, 311, 312, 313). Then, the data storage system merges the first and the at least second result sets (361, 362) into a single result set (363).</p> |
