I recently had a thought to do with DbDirectory - specifically would it
be possible to use something like Oracle's inbuilt replication to have
mutiple Reader machine being able to read the index with automatic
partitioning, redundancy and failover?
Also, what is performance like for DbDirectory
Hi,
I am looking for a in memory Database which needs high speed search
capability as well as should compress the data stored.
Currently have only one table with two columns only in my design.
Can we trick Lucene to use it for the above purpose?
I am thinking something like:
- Create a initial i
Its not a trick. And this is what lucene meant for.

Hello,I tried uninstalling and installing Lucene 2.1.0 and Tomcat 5.5. I
followed the Lucene demo instructions and set the CLASSPATH as follows:
.;C:\lucene-2.1.0\lucene-core-2.1.0.jar;C:\lucene-2.1.0\lucene-demos-2.1.0.jar
I tehn typed java org.apache.lucene.demo.IndexFiles C:\lucene-2.1.0\
Here's what I did:
1. Downloaded and unpacked 2.1.0
2. >cd lucene-2.1.0
3. >java -cp lucene-core-2.1.0.jar:lucene-demos-2.1.0.jar
org.apache.lucene.demo.IndexFiles /lucene-2.1.0/

Step 3 takes a little bit to run. You can point this at any
directory you want to index
4. >ls

Thanks Mathieu!
Didn't realise this was avalaible before you mentioned it.
Did comparative tests, and it is as fast or much faster, thanks to
caching, depending on the length of the prefix. Hey, it even works with
wildcard within the "search string".
Thanks again! Isn't Lucene wonderful!

Be very clear what you want Lucene to do. What your database
schema is and whether the columns are indexable is totally
irrelevant to your Lucene index. What is relevant is how you
construct your lucene index to solve the underlying problem.

The lack of line breaks makes it virtually impossible to read

This is a classpath issue. Please go back through the directions
very carefully. My example of classpath is for my Operating System
(OS X). You will need to configure you classpath appropriate for you

I am new to Lucene and I have been reading the book "Lucene In Action",

When searching for a word through an index is there any way to know in
which positions (may be more than one) of each document that word was
found?
The index is constructed in the following way:

Hi,
1. I am dealing with the logs files and have to index the whole file (the
attempt to increase setMaxFielldLength eventually causes out of memory

What is the most efficient way to handle this situation?

Hi Tanya,
I think one option is to index each log file with 2 fields, the name of
the log file and a line of your log. This way you can do a query like
this: +log_file_name:"log1" +line:"word1" -(+line:"word1" +line"word2")
Hope it helps,

If you are using Oracle 10g you can get the advantage of using

My very simple analyzer produces tokens made of digits and/or letters only.
Anything else is discarded. E.g. the input "smith,anna" gets tokenized as 2
tokens, first "smith" then "anna".
Say I have indexed documents that contained both "smith,anna" and
"smith,annanicole". To find them, I enter th
After taking a quick look, I don't see how you can do this without
modifying the QueryParser. In QueryParser.jj you will find the conflict

trigger a wildcard term match on the whole piece.
This is again caused by the fact
