Hi Chris,
I've not thought about that. I'm almost done with my

Hi,
Thank you all so much for the crash course in Java for
Beginners. Indeed the
last time I used java was 1996... Lol. But I'm getting
now very close. It is
all about the right declarations of classes and
includes at the correct
location. I have almost done it. I will publish my
code to the commu
I noticed the following code that builds the "docMap" array in
SegmentMergeInfo.java for the case where some documents might be deleted from
an index:
// build array which maps document numbers around deletions
if (reader.hasDeletions()) {
int maxDoc = reader.maxDoc();

Hi, Klaus, thanks.
You can simply use DBSight to create the index. It's in Lucene's
standard format.
And you can control index field type, analyzers, how to select data
from database, number of java threads, etc, just by web UI. No coding
is needed. We have a user who didn't know Lucene at all, an
Might be interesting to know if it crashed on 2 docs if you ran it
with heap size of 512Mb. I guess you've already tried with default
merge values. Shouldn't need to optimize after every 100 docs. jdk
1.3 is pretty ancient - can you use 1.5?
I'd try it with a larger heap size, and then look
Hi,
I can see that this has been up before, but I still hope to get some
advice based on my specific environment.
I index some documents with 26 fields in them. The size 1 indexed
documents is 4mb, so it shouldn't be overwhelming amounts of data
compared to what I have heard lucene can do.

Apologies
Interesting this is not the Form to discuss about HOW to Debugging with
Eclipse
So I suggest u to use the Help tab in Eclispe Ide.
Hint : First set the Break point on hte code and then use Use the Debug

this is a Lucene Form Guys

Sounds to me that all you need is to AND rather than OR your search terms.
QueryParser qp = new QueryParser("keywords", analyzer);
qp.setOperator(QueryParser.DEFAULT_OPERATOR_AND);
Query q = qp.parse(words);
where analyzer is just the standard one.

Lucene seems to tokenize the keywords with multiple words like(MAIN BOARD) as

Also Hibernate, you can use Eclipse as an IDE, with the Hibernator
plugin to create objects cleanly from your MySQL database and then a few
lines will fetch an object which you could then be passed to Lucene for
indexing.
