People..
I have a class that searchs for some documents in an existing index
(see the code below). It works fine when I run it on a 1.4 JVM but it throws
a NullPointerException (or crashes the JVM, in another computer) when I run
it on a 1.3 JVM.
I'm using Lucene 1.3rc1 and the exception/crash occurs in the
"search" method.
Is it a bug ? Should I be doing something else ? Have you been using
1.3rc1 on 1.3 JVMs ?
public static void searchIndex(String path, String field, String queryStr,
String retField) {
try {
Searcher searcher = new IndexSearcher(path);
MyOwnAnalyser analyser = new MyOwnAnalyser();
Query query = QueryParser.parse(queryStr, field, analyser);
Hits hits = searcher.search(query); //, filter);
for(int i=0; i<hits.length(); i++) {
Document doc = hits.doc(i);
float score = hits.score(i);
System.out.println("Found document \"" +
doc.get(retField));
}
} catch (Exception e1) {
e1.printStackTrace();
}
}
