_Could you further post your Analyzer Setup/Query Building code from
BOTH apps. _
there is only one code.It is the same for web and for standalone.
And it is exactly the real problem!!the code is the same,libraries are
the same,query index etc etc. are the same.
This is the class that create index
public class AlternativeRDFIndexing {
private Analyzer analyzer;
private Directory directory;
private IndexWriter iwriter;
private WordNetSynonymEngine wns;
private AlternativeResourceAnalysis rs;
public ArrayList<String> commonnodes;
//private RDFinder rdfind = new RDFinder("RDFIndexLucene/",new
String[] {"name"});
// public boolean Exists(String node) throws ParseException, IOException{
//
// return rdfind.Exists(node);
// }
public AlternativeRDFIndexing(String inputfilename) throws
IOException, ParseException{
commonnodes = new ArrayList<String>();
// bisogna istanziare un oggetto per fare analisi sul documento rdf
rs = new AlternativeResourceAnalysis(inputfilename);
ArrayList<String> nodelist = rs.getResources();
int nodesize = nodelist.size();
ArrayList<String> sourcelist = rs.getsource();
int sourcesize = sourcelist.size();
//sinonimi
wns = new WordNetSynonymEngine("sinonimi/");
//creazione di un analyzer standard
analyzer = new StandardAnalyzer();
//Memorizza l'indice in RAM:
//Directory directory = new RAMDirector();
//Memorizza l'indice su file
directory = FSDirectory.getDirectory("RDFIndexLucene/");
//Creazione istanza per la scrittura dell'indice
//Tale istanza viene fornita di analyzer, di un boolean per
indicare se ricreare o meno da zero
//la struttura e di una dimensione massima (o infinita
IndexWriter.MaxFieldLength.UNLIMITED)
iwriter = new IndexWriter(directory, analyzer, true, new
IndexWriter.MaxFieldLength(25000));
//costruiamo un indice con solo n documenti: un documento per nodo
for (int i = 0; i < nodesize; i++){
Document doc = new Document();
//creazione dei vari campi
// ogni documento avrˆ
// un campo name: nome del nodo
// indicazione di memorizzazione(Store.YES) e indicizzazione
con analyzer(ANALYZED)

//if (sourcelist.contains(node)) break;

MARCO LAZZARA
Things that could help us immensely here.
Can you post your indexReader/Searcher initialization code from your
standalone app, as well as your webapp.
Could you further post your Analyzer Setup/Query Building code from
both apps.
Could you further post the document creation code used at indexing
time? (Which analyzer, and which fields are indexed/stored)
Give us this, and I'm pretty darn sure we can nail down your issue.

New shell?
_*Are you sure the index is the same - what do IndexReader.maxDoc(),
numDocs() and getVersion() say, standalone
and in tomcat?
*_What do you mean with this question??
IndexReader ir = ...
System.out.printf("maxDoc=%s, ...", ir.maxDoc(), ...);
and run in tomcat and standalone. To absolutely confirm you're
looking at the same index, and it has documents, etc.
