Lucene-analyzer 3.3.0 and Lucene snowball 3.0.1
Hello all,
I beginning with an application and nobody knows with Lucene-analyzer 3.3.0.jar and Lucene snowball 3.0.1.jar are both included
Its do same thing ?
I how can I be sure that excluding Lucene-snowball jar in my application, it is not used (the idea that it is Lucene-analyzer is used instead).
Thank best regards
Bien cordialement,

Objet : Lucene 4.0.0 - find offsets for phrase queries
Hi all,
I use Lucene 4.0.
I try to find offsets for phrase queries.
My code works then I search for one word but then I call it for some phrase I didn't get offsets.
termsEnum.seekExact returns false for phrase queries.
reader = DirectoryReader.open( mIndexDir );
IndexSearcher searcher = new IndexSearcher(reader);
QueryParser parser = new QueryParser(Version.LUCENE_40, mField, mAnalyzer);
Query query = parser.parse(aQuery);
TopScoreDocCollector collector = TopScoreDocCollector.create(100, true);
searcher.search(query, collector);
ScoreDoc[] hits = collector.topDocs().scoreDocs;
for(int i=0;i<hits.length;++i) {
int docId = hits[i].doc;
Document d = searcher.doc(docId);
Terms tfvector = reader.getTermVector(docId, "contents");
if( tfvector != null )
{
TermsEnum termsEnum = tfvector.iterator(null);
if ( termsEnum.seekExact(new BytesRef( aQuery.toLowerCase() ), false ) )
{
DocsAndPositionsEnum dpEnum = null;
dpEnum = termsEnum.docsAndPositions(null, dpEnum);
if( dpEnum != null )
{
int freq = dpEnum.freq();
int maxOcc = 20;
while( freq-- > 0 && maxOcc-- > 0 ) {
dpEnum.nextPosition();
System.out.println("Start offset " + dpEnum.startOffset() + " End offset " + dpEnum.endOffset());
}
}
}
What is the problem?
Thanks in advance, Vitaly.

Hello Steve,
Sorry for the 1st point.
No it is an old version of solr 3.3.0 and Maven/Ivy/Gradle not used, the library has been added by hands by hands
By another developer.
Do you have an idea if I can remove snowball without worries ?

Hi Adrien,
Three comments and a question:
1. From <http://people.apache.org/~hossman/#threadhijack>:
When starting a new discussion on a mailing list, please do not reply to
an existing message, instead start a fresh email. Even if you change the
subject line of your email, other mail headers still track which thread
you replied to and your question is "hidden" in that thread and gets less
attention. It makes following discussions in the mailing list archives
particularly difficult.
2. If you're beginning a new application, start with a more modern version of Lucene: 4.0.
3. If you must use an older version of Lucene, don't mix versions!
Question: where do your Lucene jars come from? That is, did you download the binary distribution? Or are you using Maven/Ivy to download from a Maven repository? Or . ?
