Hey folks,
I am a new Lucene user , I used the following after indexing:
search(searcher, "W. Chan Kim");
Lucene showed me hits of documents where "channel" word existed. Notice that
"Chan" is a part of "Channel" . How do I stop this ?
I am keen to find the exact word.
I used the following, b
how
queries parse using various analyzers. It's an invaluable tool...

This shows me the item value. Now I wanna see the score related to this
item, how do I get that?

Hey Guys,
I just finished up using Lucene in my application. I have data in a database
, so while indexing I extract this data from the database and pump it into
the index. Specifically , I have the following data in the index:

Hey Guys,

How can I use FieldCache ? an example ?

I have also done some of the optimizations that are mentioned on the Lucene
website.

Can someone please tell me how to cache results in Lucene ? I know the
classes, but I don't know how to go about it.

Shall I setMergeFactor = 2 ?
Slow indexing is not a bother.

I get:
+contents:Harvard +contents:Business + contents: Review
Can I just add:
+contents:Harvard +contents:Business + contents: Review +itemID=id ??
That query would just return one document.

Any clues ? I can't find any examples on query building .

I did this yesterday. Manually appended an extra field to the query. It
works fine.

Hey guys,
I was wondering if there is a way to retrieve score of a field in a document
?
If my document looks like this:
{itemID},{field 1},{field 2}
I'd like to get score of individual fields 1 and 2 rather than the score of
the entire document.
Is it possible ?
thanks,
AZ
Hi,
Does anyone know how to retrieve the score of an individual field instead of
doing:
hits = score(i); This will get me the entire score of the document. I'd like
to get the score of a single field by specifying the field name.
thanks,
AZ
On 7/31/07, Askar Zaidi <[EMAIL PROTECTED
To be more specific:
I want to retrieve the scores of individual fields inside a document so that
I can manipulate the score of one field. This is the requirement of my
application. After the manipulation I can add these scores and then show the
total.
thanks,
AZ
On 7/31/07, Askar Zaidi
other 3 fields ? Will that help
? Would there be a way to bring down the score of the contents field ?

Boosting of a term in the query so that would mean,
"apache^4 jakarta"
This means I am more keen to find apache than jakarta. I am keen to boost
the score of a field, how can that be done ?

Hey Guys,
Quick question:
I do this in my code for searching:
queryParser.setDefaultOperator(QueryParser.Operator.AND);
Lucene is OR by default so I change it to AND for my requirements. Now, I
have a requirement to do OR as well. I mean while doing AND I'd like to
include results from OR too .
Hey Guys,
I am trying to do something similar. Make the content search-able as soon as
it is added to the website. The way it can work in my scenario is that , I
create the Index for a every new user account created.
Then, whenever a new document is uploaded, its contents are added to the
users I
Thats exactly what I do. The moment something is added to the database , I
add it to the lucene index of the user. Upon new account creation, open a
new lucene index for this new user. Whenever something is uploaded, just add
it to the index.

I have indexed around 100 M of data with 512M to the JVM heap. So that gives
you an idea. If every token is the same word in one file, shouldn't the
tokenizer recognize that ?
Try using Luke. That helps solving lots of issues.

1) I don't understand why the index would get corrupted. We store huge data
and meta-data using Lucene.
2) For this, I synced Lucene with the DB operations. If you use Hibernate,
theres an API for that. Or, you could just write your own factory methods to

Yes. Every time a user updates a piece of information, you do the update in

that does this mapping. I am not sure why you plan to store data in the
Index ?? Storing data is the DBs job, searching is the Index job. I would
