摘要: Supporting full-text query in an XML mediator is a difficult problem. This because most data-sources do not provide keyword search and ranking. In this paper, we report on the integration of main functionalities emerging XQuery Text standard XLive, full XML/XQuery mediator. Our approach to index keywords virtual documents views. Selected are demand mapped data source objects. Thus, selection operator efficiently extended support Keyword result ranking integrated. We rank results using relevance formula adapted XPath, based number elements distance from searched nodes.
