Subject Re: search exception in servlet!Please help me
Date Wed, 04 Aug 2004 00:44:38 GMT
Where did you get 'i'?   Keep in mind that using Hits.doc(n) intends 
'n' to be a document *id*, not the iteration through the Hits 
collection.  This is a very common mistake, and I'm guessing one you've 
made here.
