With the rise of Web search engines, processing keyword search over XML and XML streams has drawn much attention from many researchers. Compared to conventional query methods, keyword search has several benefits for its simplicity and its user-friendliness in querying XML databases. Therefore, a great deal of effort has been put on this search paradigm by trying to improve the quality of search result of pure keyword search, where only keywords are allowed as a query. However, due to the vagueness of keyword search, it is hard to accurately express real search intention with just keyword search. We observe that there are many cases where the combination of path-based query and keyword search is a better choice and can deal with such challenge. To address this problem, we propose a method to integrate XPath and keyword search so that users can accurately express their search demands. The experimental results show that the proposed scheme can process queries over XML streams practically.
