All you get is 'Error occurred

Hi Otis,
Thanks for your answer on the integer issue. I was not
sure if the index was actually limited, or if it was
just the numDocs method call. I guess it really does
not matter which it is; and for me, I don't think my
index will ever get that large! I do have a couple of
questions from you

Hello,
Yes, there is a limit, but it's pretty high:

Iterating the index like that is ok, but each call do

get expensive.

Hi,
I posted this in the past:
Java has GUID's classes called java.rmi.server.UID and
java.rmi.dgc.VMID.
The UID class can generate identifiers that are unique over time within
a JVM. The VMID class provides uniqueness across ALL JVM's.
UID consists of a unique number based on a hashcode, syste

First, you should add some timing code to determine whether your

slowdown, read on...

The 2 products I mentioned are 2 rows. I get the products in
bulk by using a limit clause.

minutes compared to the 2 records I am indexin

The only time I have seen corrupted indexes is when the java process is
killed during the indexing process.
If you shutdown tomcat (or what ever you are running for java) during the

Agree. We run an index with about 2.5 million documents and around 30
fields. The indexing itself of 2 items should only take a few
seconds on a reasonably fast machine.

I need some clarification on the indexing process.
A process is initiated for indexing 1000 documents. If for some reason, the

Try to rewrite query before highlighting.
Pasha Bizhan
Use query.rewrite() to expand the query before calling
the highlighter. See the Junit test or javadocs for
the QueryTermExtractor class.

Hello,

But it seems not support wildcard searching.
I mean if I use wildcard query, it cannot highlight any terms ?
Any idea to do this or any existing example ?
