Dear Lenya team,
First of all, thank you very much for your kind responses. As Bob
mentioned, I was be able to use Search API in Lenya 1.4 via class
DefaultSearcherImpl. The snippet below is sample of my code.
[code]
DefaultSearcherImpl searcher = new DefaultSearcherImpl( );
FSDirectory directory = FSDirectory.getDirectory(
INDEX_FILE_PATH , false );
searcher.addDirectory( directory );
PhraseQuery query = new PhraseQuery( );
Term term = new Term( "body", query_string );
query.add( term );
Hits hits = searcher.search( query );
for(int i = 0 ; i < hits.length( ) ; i++ ) {
Document doc = hits.doc( i );
Enumeration en = doc.fields();
String buf = "";
while( en.hasMoreElements( ) ) {
Field field = ( Field )en.nextElement( );
buf += "key:" + field.name( ) + "=" + doc.get(
field.name( ) ) + "\n";
}
System.out.println( buf );
}
[/code]
In brief, I query documents via PhraseQuery instance. Then I get
hits as results of my query. From Hits, I could get the documents from
it. The document here is instance of class
org.apache.lucene.document.Document which contains uuid field. The
problem is I tried to get the url of each document without success. :'(
I looked into Core Modules->linking API and Standard Modules->lucene
API. I believe that I could get the url from
org.apache.lenya.cms.publication.Document but I couldn't find a way to
turn org.apache.lucene.document.Document to
org.apache.lenya.cms.publication.Document. Does I miss a thing? Is there
any clue of resource which I should refer to?
Ps.
- Feel free to use my snippet in your document if you wish. It would be
most appreciated if I could help any. :)
- Thank you in advance ;)
Best regards,
Chokchai Phatharamalai

I suppose you're probably asking about Lenya 1.2, but for the
not-quite-released 1.4 version there is the Lucene module's API --
http://lenya.apache.org/apidocs/1.4/modules/lucene/ The Lucene module
implements the Searcher interface via AbstractSearcher.java and
DefaultSearcherImpl.java
For 1.2.5 I see
http://svn.apache.org/repos/asf/lenya/tags/RELEASE_1_2_5/src/java/org/apache/lenya/lucene/SearchFiles.java
although I am not at all familar with that code.
