Abstract

A server receives a search request in a third format. The third format is a search request format. A first search query in a first format is generated. The first format is a first search query format. A second search query is generated in a second format. The second format is compatible with a format used by a second search engine. The second format is a second search query format. The search request is in the third format. The first format and the second format are different from one another. First result data comprising a plurality of first result data items, and second result data comprising a plurality of second result data items are received. A search result is generated. The generating the search result includes consolidating the plurality of the first result data items and the plurality of the second result data items.
