eXist, Lucene and XQuery

[Gustavo Corral]

Hi list,

I have some days with a problem and I hope anybody can help me. I have
developed an extension module to search documents in an eXist collection
using Lucene. The module works fine and returns a Sequence with all the
documents matching a query sorted by the score of Lucene, but when I call
the function of the module in an XQuery script, the documents don't appear
in the same order.

I have this function which take an array with the document's names as
argument and returns a NodeSet with this documents from eXist collection:

protected static NodeSet getDocuments(String[] cgDocNames, DBBroker broker)
throws XPathException
    {
        //Creamos una Secuencia para almacenar los resultados
        ExtArrayNodeSet documents = new ExtArrayNodeSet(cgDocNames.length,
1);

        //obtiene la coleccion de reportes
        Collection cdData =
broker.getCollection(XmldbURI.create(JReportsModule.REPORTSDIRECTORY_DATA_COLLECTION));

        //itera sobre los nombres de reportes
        for(int i = 0; i < cgDocNames.length; i ++)
        {
            //System.out.println(cgDocNames[i]);

            DocumentImpl cgDoc = cdData.getDocument(broker,
XmldbURI.create(cgDocNames[i].substring(cgDocNames[i].indexOf("
")+1,cgDocNames[i].length())));
            if(cgDoc != null){
                //añade el reporte a la secuencia de resultados
                documents.add(new NodeProxy(cgDoc));
            }
        }
        documents.sort(true);
        return (NodeSet) documents;
    }

In the eval function of the extension module I call this getDocuments
function and that's the Sequence eval returns. Until this moment it seems
the documents are in the correct order, but when I call the function of the
extension module in an XQuery script the documents are returned in unorder.

Is the description clear? because my english is not very good.

Thanks
