-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1 Hi all, I want to store the @xml:id of an element (facsimile) in the Lucene index, defining: <text match="//facsimile/@xml:id"/> Why don't I get any results on the following query (and what should it look like then)? //facsimile/@xml:id[ft:query(., 'something')] Best, Torsten - -- Torsten Schassan Herzog August Bibliothek, Postfach 1364, D-38299 Wolfenbuettel Tel.: +49-5331-808-130, schassan {at} hab.de http://www.hab.de; http://www.hab.de/forschung/projekte/weiss64.htm -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iD8DBQFK+rLiq4nZEP2KS4QRAlWOAJ9QjbQfX43acxLyAYaLE2lLVxT4XwCfXe1C L1YF8juMejuJu0gh8tS04Xs= =e0k5 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Torsten,
> (in general) I was aware of the fact but does this mean it is not > possible to store an attribute in the index? No, it is possible! I store @id attributes using this index definition: <lucene boost="1.0"> <text qname="@id"/> </lucene> I can query this attribute as follows: //volume[ft:query(./@id, 'frus*')] Oddly, I notice that moving the attribute outside the predicate returns no results for me either: //volume/@id[ft:query(., 'frus*')] So, I'd suggest trying (1) moving your attribute inside the predicate and (2) confirm whether you need a wildcard ('*') or other Lucene search operator to match the desired results.
