Text search engines are inadequate for indexing and searching XML documents because they ignore metadata and aggregation structure implicit in the XML documents. On the other hand, the query languages supported by specialized XML search engines are very complex. In this paper, we present a simple yet flexible query language, and develop its semantics to enable intuitively appealing
extraction
of relevant fragments of information while simultaneously falling back on
retrieval
through plain text search if necessary. We also present a simple yet robust relevance ranking for heterogeneous document-centric XML.
