Subject Problem when searching ..
Date Fri, 15 Apr 2005 07:48:14 GMT
Hi,

I am creating an index of my data that's persisted by Hibernate using
Lucene. I am running my indexer on a huge data set. My indexing takes
1312805ms. At the end of which I get a 26,266KB directory. 

I can view the contents of my index directory using Luke.

When I copy my webapp under Tomcat and try to search on it I get the
following exception:

java.io.FileNotFoundException: C:\Program Files\Apache Software
Foundation\Tomcat 5.5\webapps\tan\tan-search-index\_33.fnm (The system

This is the code of my com.ac.t.managers.SearchManagerImpl.search
function:

	public Hits search(String indexPath, String queryString, String
entity)
		throws IOException, ParseException
	{
		IndexSearcher indexSearcher = new
IndexSearcher(indexPath); <--This is the line where it throws the
exception.

		if(queryString == null) 
		  queryString = "";

		Query query1 =
QueryParser.parse(queryString,"content",analyzer);
		
		Term term = null;
		if(entity.equals("product"))
		  term = new Term("entity","product");
		else
		if(entity.equals("category"))
		  term = new Term("entity","category");
		  
		TermQuery query2 = new TermQuery(term); 
		BooleanQuery bq = new BooleanQuery();
		bq.add(query1, true, false);
		bq.add(query2, true, false);
		
		log.debug(query1.toString());
		log.debug(query2.toString());
		log.debug(bq.toString());

		return indexSearcher.search(bq);
	}


What am I doing wrong while searching? Why is the exception being
thrown?
