How does Federated Query Server sort query results?
unlimited number of sort levels may be specified. Each level may sort on one of the following elements of a result – URL, title, summary, relevance score, date, size, language, author, category, image URL, image ALT, reference string, type string, reference number, type number, content repository name, or any one of 10 user defined elements. Usually, the first level sort is by relevance score, as this is the order in which results are normally returned from content repositories.
