*** JUNK MAIL ***Re: [opencms-dev] search xmlcontent

[Claus Priisholm]

I think you should be able to get what you need just by making a new 
Lucene document factory class for the document types in question. And 
then set it in the setup-file (documenttype definition).

>> The first step is to make sure the Lucene index actually support the kind of query you want to make. I.e. the contents of the specific tags from your xmlcontent must be present in a separate Lucene index field. Per default OpenCms extracts all text from the contents and put into the contents field in the Lucene index, so you cannot limit the search to only look at specific parts of the xmlcontens.
