Of course, these are programming errors nothing really related to
Lucene.

Hits hits;
Int hitCount =3D hits.length

This does not make sense. You have just declared hits. It must be
created before using it.

The second error should disapper if you add throws declaration or
try/catch block.

By the way, avoid asking such questions in this forum because the
questions are not related to Lucene!!

	{
		System.out.println("hi");
=09
=09
Hits hits;
int hitCount =3D hits.length();
for (int i=3D0;i<hitCount;i++) {
   int docId =3D hits.id(i) ;
 =20
}=20
}
}

C:\Documents and Settings\Sumit\Desktop>javac db/comm.java
