A computer initializes a configuration specified in an extensible markup language (XML) configuration file. The XML configuration file specifies at least one data source, a dimension to map each item of a plurality of items that include products, product accessories, or product support documents in the at least one data source, and a display priority for each item. Next, the computer reads data from the at least one data source specified in the configuration file. The computer generates an XML dimension hierarchy file for the read data using the configuration file. The XML dimension hierarchy file includes a dimension node for each item. Each dimension node has at least one property attached to each item and at least one synonym that is searchable to index each item. Finally, the computer preprocesses the XML dimension hierarchy file to index the at least one data source.
