Hi.
When I add new documents to my index, I sometimes end up with a larger
number of segments than i theoretically should be able to. I use all
the default settings.
If I have understood this right I should never experience more than nine

Hi All,
I m new to Lucene,
Just wondering if there is a way to realize sql 'Like' function in Lucene as
following:
Select * from user_table where username like '%abc%'
I have checked with wildCardQuery, but it can not start with a '%'.
What about RegexQuery? How to use it?
Thank you very muc
Hi Kirin,
Once you've updated an index using IndexWriter or IndexReader you just need
to close and re-open your IndexSearcher so that searching includes the
changes. There is a great library callled LuceIndexAccessor at the link
below that manages this for you. It creates an IndexReader/Writer

Hi,
at the moment we match a query with a document with explain. We consider the
document as matched if the Explanation.getValue() is above a certain value (>

Now we want to use Search.search(Query, HitCollection).

Hello,
I am having problems using lucene 1.9.1. I was using 1.4.3 successfully, and
tried upgrading to 1.9.1. As I changed my source code so I would no longer be
invocating deprecated methods, the application no longer worked properly, i.e.
the IndexModifier was no longer storing documents. He
AFAIK optimize() will merge existing segments into single segment,
regardless of the value of maxMergeDocs.

I'm going to take a shot in the dark and guess that the field in question
is analyzed using some form of Stemming which strips off trailing "e"
characters (Porter Stemmer seems to do this).
In the past, there was a bug in the way WildcardQuery works, so that the
metacharacter "?" matches 0 or 1 c
I think I've fixed my own problem. I was using 1.4.3 in my code and
the index was using 1.9.1. I updated and no longer get the error.
Is this consistent with other people's experience though? I want to
make sure this was actually the problem so the error doesn't
resurface later.

Hi!
I have a question concerning the interal searching behavior of lucene. How does
lucene get a hit.
If I search for the a term, will each index document be checked for this term
or is there an internal relation between terms and lucene documents?
Thanks for any advice.

The code needs a minor change. Replace

with
