Hey, I am looking for anyone with some experience or insight into so called "full-text" searches on xml document text nodes. I have been working through full-text examples using NUX (http://dsd.lbl.gov/nux/ which uses saxon for XQuery implementation and Lucene for full-text indexing and searching via an extension) and i seem to be heading in the right direction but am not quite there yet - so i am first interested in know whether what i want to do is possible using using XQuery: ...given a document with text content that is spread out between elements as such (following xml fragment), this can be easily rendered out to html (and other formats too) where a "block" translates to a "p" and an "inline" translates to a "span" -> paragraphs then can have an html @class (via an optional block-properties/block-style element) and the spans can have a constructed @style (via a set of inline-properties/inline-style elements), so the text of the following doc fragment would "read" in html as "This is a sample of a basic paragraph with inline styles in WordML" with various translated html styling: ... </block> <block> <block-properties> <block-style name="Heading1"/> </block-properties> <inline> <text>This is a sample of a </text> </inline> <inline> <inline-properties> <inline-style name="i"/> </inline-properties> <text>basic </text> </inline> <inline> <inline-properties> <inline-style name="i"/> <inline-style name="color" value="FF0000"/> </inline-properties> <text>paragraph</text> </inline> <inline> <inline-properties> <inline-style name="i"/> </inline-properties> <text> </text> </inline> <inline> <inline-properties> <inline-style name="b"/> <inline-style name="i"/> </inline-properties> <text>with</text> </inline> <inline> <inline-properties> <inline-style name="i"/> </inline-properties> <text> inline </text> </inline> <inline> <inline-properties> <inline-style name="i"/> <inline-style name="u" value="single"/> </inline-properties> <text>styles</text> </inline> <inline> <text> in WordML.</text> </inline> </block> <block> ... so the question is can i (from a block node context) return the set of inline nodes where any inline/text meets a search phrase. for instance in the preceding example can i get the inline elements (the first three in this case) that contain the phrase "This is a sample of a basic paragraph" ??? and eventually i want to add the associated search -result "highlighting" to those inline elements where the match was found. So, is this within the scope of XQuery full-text search capability and i just need to craft the XQuery properly (likely with some FLWR expression) or is full-text search limited to text within a single node? thanks, Peter
