I have a strange problem...I have indexed a couple of Web pages (used htmlparser for HTML to text conversion)
and I can see the index created. When I search for a term, lucene returns the hits and score. But when I try to
retrieve the document (hits.doc(int)) it gives me the following error
"Exception in thread "main" java.io.IOException: The system cannot find the path specified"
at java.io.RandomAccessFile.readBytes(Native Method)
at java.io.RandomAccessFile.read(Unknown Source)

at org.apache.lucene.search.IndexSearcher.doc(Unknown Source)
at org.apache.lucene.search.Hits.doc(Unknown Source)
at WebPageSearcher.main(WebPageSearcher.java:86)
Here is sample code
indexing: (which works fine)
public void index(String uid, String title, String text) {
try {
IndexWriter writer = new IndexWriter("d:\\tomcat\\webapps\\ROOT\\url_index", analyzer, true);
Document document = new Document();
document.add(Field.Keyword("uid", uid));
document.add(Field.Text("title", title));
document.add(Field.UnStored("pagebody", text));
writer.addDocument(document);
} catch (Exception e) {
e.printStackTrace();
}
}Searching: (gives error on the line hits.doc(i))
..........
..........
searcher = new IndexSearcher("d:\\tomcat\\webapps\\ROOT\\url_index");
Query query = QueryParser.parse(queryString, "pagebody", new StandardAnalyzer());
hits = searcher.search(query);
for (int i=0;i< hits.length();i++) {
Document doc = hits.doc(i);
String doctitle = doc.get("title");
String url = doc.get("uid");
}
}
I appreciate your time and help Thanks..Shanti
